Choosing the right size yoga ball for pregnancy is very important. It helps you sit right and do exercises safely. Many people ask, “How big of a yoga ball for pregnancy?” and “How to size a pregnancy ball?” The basic idea is simple: your height tells you the right size ball to pick. Most pregnancy yoga balls come in sizes like 55 cm, 65 cm, and 75 cm. Each size is good for a different height range. Picking the best birth ball size for height makes using the ball easier and safer for you and your baby. This guide will help you find the perfect size.

Why Ball Size Matters During Pregnancy
Using an exercise ball during pregnancy can help in many ways. It can ease back pain. It can make sitting more comfortable. It can also help you get ready for labor. But all these good things only happen if you use the right size ball. A ball that is too big or too small can be hard to use. It might not help your posture. It could even be unsafe. Picking the proper exercise ball size during pregnancy is key to getting the most benefits.
Good Things About Using a Ball
Using an exercise ball feels good for many expectant moms.
* It helps your back feel better. Sitting on a ball lets your hips move a bit. This takes pressure off your lower back.
* It helps you sit up straight. A ball makes you use your core muscles gently. This helps with good posture.
* It makes your pelvis ready. Gentle bouncing and hip circles on the ball can help loosen your hips and pelvis. This is good for labor.
* It can help the baby get into a good position. Sitting upright and doing gentle movements can help the baby move head-down.
* It’s comfy for sitting. Many pregnant women find sitting on a hard chair is not comfy anymore. A ball is softer and lets you move.
* It helps with simple exercises. You can do light stretches and moves on the ball. This keeps you active.
All these benefits depend on the ball being the right size for you.
Finding the Right Ball Size
The main way to choose the right size exercise ball for pregnancy is based on how tall you are. Yoga ball sizes are usually measured by their diameter. That is the distance straight across the middle when the ball has air in it. The sizes are given in centimeters (cm). Common sizes are 55 cm, 65 cm, and 75 cm.
Using a pregnancy ball chart by height helps you see which size matches your height. These charts are a great starting point for choosing the right exercise ball for pregnancy.
Pregnancy Ball Chart by Height
Here is a general guide. Remember, this is a starting point. You should always do the “sitting test” too.
| Your Height | Recommended Ball Size | Yoga Ball Diameter for Expectant Moms |
|---|---|---|
| Under 5 feet 2 inches (157 cm) | 55 cm | 55 cm |
| 5 feet 2 inches to 5 feet 10 inches (157 cm to 178 cm) | 65 cm | 65 cm |
| Over 5 feet 10 inches (178 cm) | 75 cm | 75 cm |
This table gives you the recommended birth ball size based on how tall you are. For example, if you are 5 feet 5 inches tall, the chart says a 65 cm ball is likely the best birth ball size for height for you. If you are 6 feet tall, a 75 cm ball is probably right.
How to Check the Size: The Sitting Test
Looking at a chart is helpful, but the best way to know if the ball is the right size is to sit on it. This is the most important step in how to size a pregnancy ball. The sitting test is simple.
- Put enough air in the ball so it feels firm but not too hard. Do not fill it to the very maximum printed size right away. Fill it until it feels like a good, round ball.
- Sit on the ball like you would sit on a chair. Put your feet flat on the floor. Your feet should be shoulder-width apart for balance.
- Look at your knees and hips. Your knees should be a little lower than your hips. Or, your hips and knees should be about level.
This creates a shape that looks like your hips are slightly above your knees. Or, your upper legs (thighs) should slope slightly downward from your hips to your knees. Your knees should bend at about a 90-degree angle or a little more (like 90 to 100 degrees).
What the Sitting Test Tells You
- Knees lower than hips (or level): This means the ball is likely the correct size. Your back can stay straight, and your pelvis is in a good spot. This is the proper exercise ball size during pregnancy.
- Knees much higher than hips: The ball is too small. Your body is scrunched up. This is not good for your back or pelvis. You need a bigger ball.
- Knees much lower than hips: The ball is too big. You might feel like you are sinking into it. Your feet might not be flat on the floor easily. This can make you unsteady. You need a smaller ball.
This sitting height on birth ball is crucial for comfort and safety. It ensures your spine is aligned well and your hips are open.
Adjusting the Ball’s Air
Sometimes, you can make a ball that is almost the right size work by changing the amount of air in it.
* If the ball is slightly too big, you can let out a little bit of air. This makes the ball a little softer and lower. But do not let out too much air. The ball still needs to be firm enough to hold you up safely.
* If the ball is slightly too small, you can add a little more air. This makes the ball a little firmer and taller. But do not pump it up past its suggested size. This can damage the ball or make it pop.
Adjusting air is a fine-tuning step. It does not fix a ball that is way too big or too small based on your height. The yoga ball diameter for expectant moms needs to be close to the right size for your height first.
More Details on Choosing the Right Ball
Choosing the right exercise ball for pregnancy is about more than just height. Think about where you will use it and what you will use it for.
Where You Will Use It
Will you use it at a desk? Make sure the height lets you work comfortably. Will you use it in your living room? Think about how it fits in the space.
What You Will Use It For
- Just for sitting: Comfort is key. The sitting test is most important here.
- For light exercise: The ball needs to be stable. Make sure it does not feel wobbly when you move on it. Proper inflation helps with stability.
- For labor: A good birthing ball size guide often puts more focus on being able to rock or bounce gently and safely. The 90-degree rule (or slightly more) from the sitting test helps here too. It lets your hips move freely.
Thinking About Your Weight
Yoga balls have a weight limit. During pregnancy, you will gain weight. Make sure the ball you choose can safely hold your weight, plus some extra for the baby. Most quality exercise balls can hold 300-600 pounds, which is plenty for pregnancy. Always check the weight limit on the product box or info.
Quality Matters
Get a ball made from strong, thick material. Look for features like “anti-burst” or “burst-resistant.” This means if the ball gets a small hole, it will deflate slowly instead of popping fast. This is a very important safety feature for using an exercise ball during pregnancy. A good quality ball will also keep its shape and not stretch too much when you sit on it. This helps keep the correct size.
When the Ball Size Is Wrong
Using the wrong size ball can cause problems.
If the Ball is Too Small
- Your knees will be much higher than your hips.
- This makes your back round instead of straight. This can cause more back pain, not less.
- Your hips feel cramped. It is hard to do hip movements needed for labor prep.
- You might feel less stable because your center of gravity is off.
If the Ball is Too Big
- Your knees will be much lower than your hips.
- Your feet might not sit flat on the floor. This makes you feel shaky.
- It is hard to sit up straight. You might slouch.
- It is harder to control your movements on the ball.
- Getting on and off can be harder and less safe.
Getting the recommended birth ball size for your height helps avoid these issues. It makes sure the ball supports your body the right way.
Step-by-Step Guide to Sizing Your Pregnancy Ball
Let’s put it all together into simple steps for how to size a pregnancy ball.
Step 1: Measure Your Height
Stand straight against a wall. Have someone mark your height. Measure from the floor to the mark. Note your height in feet/inches or centimeters.
Step 2: Look at the Size Chart
Use a pregnancy ball chart by height, like the one in this guide. Find your height range. See the suggested yoga ball diameter for expectant moms. This gives you the starting size (like 55 cm, 65 cm, or 75 cm).
Step 3: Get a Ball Close to That Size
Buy or borrow a ball that is the size the chart suggests.
Step 4: Inflate the Ball
Use a pump to put air in the ball. Do not inflate it to the rock-hard maximum right away. Inflate it until it is firm and round, but still has a little give. Some balls have a specific diameter marking to help you see the size as you inflate.
Step 5: Do the Sitting Test
Sit on the ball with your feet flat on the floor, shoulder-width apart.
Look at your knees and hips.
Are your knees level with or slightly lower than your hips? If yes, the size is likely correct. Your thighs should slope down gently.
If your knees are much higher than your hips, the ball is too small.
If your knees are much lower than your hips, the ball is too big.
Step 6: Adjust Air if Needed (Small Adjustments Only)
If the fit is almost right, you can add a little air (if slightly too small) or let out a little air (if slightly too big).
Re-do the sitting test after adjusting the air.
If a small air adjustment does not make it right, you need a different size ball.
Step 7: Check Comfort and Stability
Sit on the ball for a few minutes. Do you feel stable? Is it comfortable? Can you move slightly (gentle bounces, hip circles) without feeling wobbly? If yes, you found the proper exercise ball size during pregnancy.
This process helps you go from the general exercise ball size for pregnancy based on height to the specific best birth ball size for height that feels right for you.
Caring for Your Pregnancy Ball
Once you have the right size ball, take good care of it. This keeps it safe and makes it last longer.
- Keep it Clean: Wipe it down with mild soap and water if needed. Let it air dry.
- Keep it Away from Sharp Things: Be careful of pet claws, jewelry, or sharp furniture edges that could poke a hole.
- Do Not Over-Inflate: Always check the ball’s size limit when adding air. Overfilling can damage the ball.
- Check Air Levels: Balls can slowly lose air over time. Check the inflation every so often. Add air if it feels too soft or too low when you sit on it.
- Store Properly: When not using it, keep it away from direct sunlight or extreme heat/cold.
Taking care of the ball ensures it stays the correct yoga ball diameter for expectant moms and remains a safe tool.
Using the Ball Safely
Even with the right size ball, safety is key.
* Always have a clear space around you.
* Make sure the floor is not slippery.
* Wear shoes with good grip, or use the ball on a rug or mat.
* Get on and off the ball slowly and carefully.
* Do not do risky or fast movements. Keep movements gentle, especially when you are pregnant.
* If you feel dizzy or unsteady, stop using the ball.
* If you have any health worries or pregnancy issues, talk to your doctor or midwife before using an exercise ball.
Following these safety tips and using the recommended birth ball size helps you use the ball with peace of mind.
Yoga Balls vs. Birthing Balls
Sometimes, the terms “yoga ball,” “exercise ball,” and “birthing ball” are used to mean the same thing. For pregnancy and labor, they are often the same product. However, when looking for a ball to use during pregnancy and potentially labor, look for balls known for their strength and anti-burst features. These are often marketed as “birthing balls” or high-quality “exercise balls.” The size guidelines (like the pregnancy ball chart by height and the sitting test) apply no matter what it is called. The key is finding the correct yoga ball diameter for expectant moms that works for your height and provides the right sitting height on birth ball.
More About Inflation
Getting the right amount of air in the ball is part of finding the proper exercise ball size during pregnancy.
* When you first get the ball, it might be folded up. Inflate it almost fully, then let it sit for a day. The material will stretch a bit. Then, add more air the next day to the right level for the sitting test.
* Do not use a high-pressure air pump like one for car tires. Use the pump that came with the ball or a hand/foot pump designed for exercise balls.
* Some balls have a line or patch that shows the maximum diameter. Do not inflate past this line.
* The ball should be firm enough to support you well, but not feel like a rock. It should have a little bit of bounce or give.
Proper inflation helps keep the exercise ball size for pregnancy correct and safe.
Specific Heights and Ball Sizes
Let’s look at some examples to make the pregnancy ball chart by height even clearer.
- If you are 5 feet (152 cm) tall: The chart suggests a 55 cm ball. When you sit on it, your knees should be level with or a little below your hips.
- If you are 5 feet 6 inches (168 cm) tall: The chart suggests a 65 cm ball. This size should give you the right sitting height on birth ball, with knees lower than hips.
- If you are 5 feet 11 inches (180 cm) tall: The chart suggests a 75 cm ball. This should allow your thighs to angle down slightly from your hips.
Remember, these are guidelines. Always do the sitting test to confirm the best birth ball size for height for your unique body. People with longer legs for their height might need a slightly bigger ball. People with shorter legs might need a slightly smaller one. The sitting test takes your body shape into account.
Summary of Choosing the Right Ball
Finding the correct size yoga ball for pregnancy is simple when you know how.
1. Start with your height and a size chart (like the pregnancy ball chart by height) to get the general recommended birth ball size (55cm, 65cm, or 75cm). This gives you the starting yoga ball diameter for expectant moms.
2. Inflate the ball to be firm but not overfilled.
3. Sit on the ball with feet flat on the floor. Check if your knees are level with or slightly lower than your hips (the sitting height on birth ball). This is the key check for the proper exercise ball size during pregnancy.
4. Adjust air slightly if needed, or get a different size ball if the fit is very wrong.
5. Choose a quality ball with anti-burst features.
Following this birthing ball size guide helps ensure you have a safe and effective tool to use throughout your pregnancy and maybe even during labor.
Frequently Asked Questions (FAQ)
Here are some common questions about choosing and using a pregnancy ball.
Q: Can I use a regular exercise ball instead of a special birthing ball?
A: Yes, generally. Many exercise balls are fine. The key is to make sure it’s the right size for your height and is good quality. Look for balls labeled “anti-burst” or “burst-resistant” for safety. The exercise ball size for pregnancy guidelines (based on height and the sitting test) apply to any ball you use.
Q: What if I am between sizes on the chart?
A: If you are right on the edge of a size range (like 5 feet 2 inches, which is the start of the 65 cm range), you might try the larger size first. Then, do the sitting test. Sometimes, letting out a little air from the bigger ball works better than overinflating a smaller one. The sitting height on birth ball is your final check.
Q: How much air should I put in the ball?
A: Inflate it until it feels firm but has a little give. Do not inflate it until it is hard as a rock. You should be able to push your thumb into the surface a little bit. Overinflation can make the ball unsafe and uncomfortable. Always check the ball’s maximum size limit. Getting the right amount of air helps ensure the yoga ball diameter for expectant moms stays correct for your height.
Q: Can using the wrong size ball hurt me or the baby?
A: Using a ball that is significantly the wrong size can be less safe. A ball that is too small might make you feel unsteady or hurt your posture, leading to more back pain. A ball that is too big can make it hard to keep your feet flat and stable, increasing the risk of falling. Always use the proper exercise ball size during pregnancy and follow safety tips.
Q: When can I start using an exercise ball during pregnancy?
A: You can usually start using a ball whenever you feel comfortable, often from the first trimester. However, it is always a good idea to talk to your doctor or midwife before starting any new exercise or activity during pregnancy. Make sure you pick the best birth ball size for height from the start.
Q: Can the ball help during labor?
A: Many women find sitting or leaning on a birth ball helpful during labor. Gentle rocking or bouncing can help manage pain and may help the baby move down. Using the correct size ball (based on the birthing ball size guide and sitting test) is extra important during labor for comfort and safety.
Q: Does my height change enough during pregnancy to need a different size ball?
A: Your height does not change during pregnancy. Your shape and weight do change, which is why the sitting test is so important. Even if the chart says one size, your changing body might feel better on a slightly different size or require adjusting the air level. The sitting height on birth ball is key throughout your pregnancy.
Q: My feet don’t touch the floor when I sit on the size ball the chart says. What do I do?
A: This sounds like the ball is too big for you, even if your height suggests that size. Go down to the next smaller size (e.g., if the chart said 65 cm, try a 55 cm). Do the sitting test again. Your feet must be flat on the floor for stability. The sitting height on birth ball is the most important part of the birthing ball size guide.
Q: Where can I find a pregnancy ball chart by height?
A: Many online stores that sell exercise balls will have a chart in the product info. You can also find general charts like the one provided in this article by searching online for “exercise ball size chart by height” or “birthing ball size guide.” Always pair the chart info with the sitting test.
Choosing the correct exercise ball size for pregnancy makes a big difference in how useful and safe the ball is for you. Take the time to find the right fit using the size chart and the sitting test. Happy bouncing!
