How to Do the Rice Test for Breast Implants | Step-by-Step Sizing Guide

Can you really use uncooked rice to try different breast implant sizes at home? Yes! The breast implant rice test is a simple, inexpensive way to experiment with different amounts of breast volume before augmentation surgery. All you need is rice, nylon stockings, a measuring cup, and scissors.

But how do you make rice breast implant sizers, how much rice should you use for 300cc, 400cc, or 500cc, and how closely does the result resemble a real breast implant?

Let's walk through the process, step by step. We'll also show you why there may be a better way to experience different breast sizes at home.

 

What Is the Breast Implant Rice Test?

The rice test is a do-it-yourself breast implant sizing method that involves measuring uncooked rice into nylon stockings, shaping the filled stockings, and placing them inside a bra.

The idea is to approximate the additional volume associated with different breast implant sizes so you can get a rough visual impression of how a fuller breast silhouette might look on your body.

It's inexpensive, accessible, and something you can try in your own home.

"The rice test can help you visualize additional breast volume. But visualizing a size and living with that size are two very different experiences."

What Do You Need to Make Rice Breast Implant Sizers?

You'll need just four things:

• Uncooked rice

• A pair of nylon stockings or knee-high nylons

• A measuring cup, preferably marked in milliliters (mL)

• Scissors

A funnel can also make pouring the rice into the stockings easier, and rubber bands can help secure the ends.

That's it. You probably have most of these materials at home already.

How Much Rice Do You Need for Different Breast Implant Sizes?

Breast implants are measured in cubic centimeters (cc). One cubic centimeter equals one milliliter (mL) of volume.

For the rice test, you can use the following measurements as a starting point:

Implant Size	Rice Volume	Approx. US Cups
200cc	200 mL	0.85 cup
250cc	250 mL	1.06 cups
300cc	300 mL	1.27 cups
350cc	350 mL	1.48 cups
400cc	400 mL	1.69 cups
450cc	450 mL	1.90 cups
500cc	500 mL	2.11 cups

These measurements are approximate volume equivalents, not predictions of postoperative breast size. Rice packing, stocking shape, bra fit, and your existing breast tissue all influence the appearance.

For example, if you're experimenting with 400cc, measure approximately 400mL of uncooked rice for each breast.

Step-by-Step: How to Make Your Own Rice Breast Implant Sizers

Step 1: Measure your rice. Decide which volume you want to try and carefully measure the corresponding amount of uncooked rice. You'll need two equal portions, one for each breast.

Step 2: Cut the nylon stockings. Cut sections large enough to hold your measured rice while leaving enough material to secure the opening.

Step 3: Fill the stockings. Carefully pour the rice into each stocking. A funnel can help prevent spills, although as you'll see in our video, keeping rice off the kitchen counter can be an adventure!

Step 4: Secure the openings. Gather the open end of each stocking and tie it securely. You can also use a rubber band to help hold everything together.

Step 5: Shape your rice sizers. Flatten and spread the rice into a rounded shape. Try to make both sizers as similar as possible.

Step 6: Place them inside your bra. Put on a supportive bra and position the rice sizers inside. Look at yourself from the front and side, and try a fitted shirt to see how the added volume changes your silhouette.

Congratulations! You've just made your own homemade breast implant sizers.

How Accurate Is the Rice Test for Breast Implant Sizing?

The rice test can give you a rough impression of additional breast volume, but it cannot accurately predict your final appearance after breast augmentation.

There are several reasons.

Rice doesn't behave like breast tissue or silicone implants. Uncooked rice is granular and can form irregular shapes. The finished sizer may look more like a small football than a natural breast.

Getting two matching sizers can be difficult. Even when you carefully measure the same amount of rice, the stockings may stretch differently, causing variations in shape.

The sizers may be visible under clothing. Homemade rice bags can create unnatural edges, protrude from the bra, or shift around as you move.

They're not particularly convenient for extended wear. Standing in front of a mirror for a few minutes is one thing. Wearing homemade rice bags while shopping, working, or going about your normal day is another.

And most importantly, neither rice sizers nor commercially made external sizers can reproduce how a surgically placed breast implant will look and feel.

The American Society of Plastic Surgeons explains that implant sizing involves individual anatomical measurements and discussion with your plastic surgeon.

Rice Test vs. Oumènta Breast Implant Sizers: What's the Difference?

The rice test is a useful inexpensive experiment. But what if you want to do more than stand in front of a mirror?

Oumènta breast implant sizers were created to let women experience different approximate breast volumes during everyday activities.

Rather than filling stockings with rice, Oumènta uses purpose-made external sizers worn inside a specially designed pocket bra. Sizers are available in volumes from 200cc to 500cc, in 25cc increments.

That means you can compare sizes without repeatedly measuring rice and making new stockings.

More importantly, you can put on your favorite clothes, walk around, go shopping, spend time with friends, and experience how different volumes look and feel over an extended period.

"Choosing a breast implant size isn't just about how you look standing in front of a mirror. It's about how you feel experiencing that size in everyday life."

Is the Rice Test Better Than 3D Breast Implant Simulation?

Not necessarily. Each method answers a different question.

The rice test provides an inexpensive physical approximation of volume. Three-dimensional simulation can help visualize possible surgical outcomes on a screen. External breast implant sizers let you wear approximate volumes on your body.

None can guarantee a surgical result.

We've explored the advantages and limitations of all three methods in our companion article: Rice Test vs. Breast Implant Sizers vs. 3D Simulation: Which Is Best?.

Why Trying Different Breast Sizes Matters

Imagine trying a 350cc rice sizer and thinking the size looks perfect.

But would you feel the same way after wearing that approximate volume for several hours? Would you prefer something slightly larger under your favorite dress? Would 400cc feel more proportional to your frame—or more volume than you actually want?

Those are questions worth exploring before making a long-term decision.

The U.S. Food and Drug Administration emphasizes the importance of discussing expectations, implant size, and potential risks with your surgeon. Changing implant size after surgery may require another operation.

That's why gathering information about your preferences before surgery can be valuable.

The Bottom Line: Should You Try the Rice Test?

Absolutely, if you're curious about breast implant sizes and want an inexpensive way to begin experimenting with additional volume.

The rice test is easy to make, inexpensive, and can help you understand why a number such as 300cc or 400cc doesn't tell the whole story.

But don't confuse a homemade rice bag with an accurate preview of your surgical outcome.

And don't assume a few minutes in front of a mirror will tell you everything you want to know about living with a fuller breast silhouette.

Rice is great for cooking. For experiencing different breast sizes throughout your everyday life, consider a purpose-made sizing system.
