Breast Weight Calculators: How Much Do Your Boobs Weigh?
Have you ever found yourself pondering how much your breasts weigh?
It’s an unusual and curious topic that might have crossed your mind, especially when the back pain from the weight of your breasts is too much to handle!
And no kidding, some of you might have even tried putting them on a kitchen scale (since bathroom scales won’t detect weight less than 15 lbs, at least the one I have, #iykyk) and trying to see it for reality.
However, that data is not only inaccurate but also highly confusing. Fortunately, there are much better ways to find out the truth.
Below are six of the best ways to determine the weight of your breasts, including two user-friendly breast weight calculators.
And understanding your breast weight is more important than you might think. This data can be a valuable tool beyond mere curiosity.

How to Use the Simple Breast Weight Calculator?
It’s surprisingly simple to find how much your boobs weigh with our simple breast weight calculator. All you need is your bra size handy.
- Here’s how it works: enter your band and cup sizes into the calculator. Let’s say you’re a 36DD. Select “36” for the band and “36DD/E” for the cup.
The calculator will then work its magic and give you an estimated weight for each breast, the total weight for both, and the volume of one cup.
Just remember, this is an estimate, and individual variations can occur.
How does this simple breast weight calculator work?
This breast weight calculator is based on a mathematical formula used to estimate cup volume and breast weight.
You can find more information about this method on this Wikipedia page.
The formula basically calculates the volume of the hemispherical shape of the breasts. Based on that calculation, it estimates the weight of fatty tissue of the breasts (approx. 0.9 g/cm3).

How to use this calculator?
To use this breast calculator, begin by measuring the dimensions of your breasts. It’s important to perform these measurements when sitting or standing with your arms at your sides.
- Enter the measurements you’ve taken into the calculator. It will use these dimensions to calculate the volume of your breasts.
- Based on the calculated volume, the calculator will provide you with an estimated weight for both breasts.
Please note that precise measurements are crucial for accurate results. Even a slight error in the measurements can lead to significant deviations from the actual weight. If possible, consider using the help of your partner or someone you trust for more accurate measurements.
How does this advanced breast weight calculator work?
This calculator works on two key components:
- Determining Volume of the Breasts
- Calculating the Weight of the Breasts
The volume calculations are made using anatomic dimensions and a geometric volume formula.
The formula used here (as proposed by researcher Quin Qiao) is:
breast volume = π/3 × MP^2 × (MR + LR + IR − MP)
where,
- MP = mammary projection
- MR = medial breast radius
- LR = lateral breast radius
- IR = inferior breast radius
Since this formula has been scientifically tested and proven by Qiao Q, Zhon G, and Ling Y, it is very safe to assume that the volume can be predicted quite accurately using this method (given breast measurements are done correctly).
However, the second piece of the puzzle involves the calculation of breast density to determine the overall weight of your breasts.
So far, there is no mathematical or DIY way to measure breast density, as it can be measured accurately only through a procedure called a mammogram.
However, since most of us don’t have access to mammogram procedures, we are going to make an estimate. The weight of healthy breast tissue per cubic centimeter (cc) can vary, but on average, it is estimated to have a density of around 0.9 grams per cubic centimeter (g/cc).
Please keep in mind that individual variations can occur, and factors such as age, composition, and other factors may influence the density of breast tissue to some extent.
Based on this estimated density, it can calculate the weight of your breasts.
If you happen to know your breast tissue density (through imaging/mammography results), you can predict your breast weight with almost accuracy by simply multiplying your volume results from the calculator with your breast tissue density.
How to Calculate Your Breast Volume?
Several scientific methods have been developed to calculate breast volume, which have been mentioned below.
Method | How does it work? |
---|---|
Anatomic (Anthropometric) Measurement | Uses tape measures and calipers to measure breast dimensions. Also, the basis for our advanced breast weight calculator. |
Archimedes (displacement of water) | Submerges the breast to measure the water displaced, equating to breast volume. |
Imaging (mammography) | Utilizes radiographic imaging to visualize and assess breast tissue and structures. |
Grossman-Roudner device method | Employs a mechanical device for measuring breast dimensions and assessing augmentation. |
Casting | Involves creating a mold or cast of the breast to determine size and shape. |
Biostereometrics | Utilizes 3D measurement techniques, including optical scanning, for precise breast measurements. |
1. Anatomic (Anthropometric) Measurement
The anatomic measurement (also known as the anthropometric method) is one of the easiest and most convenient ways to determine the weight of your boobs.
It involves the systematic measurement of 4 parameters and can be easily done at home using a measuring tape.
The required measurements are:
- Mammary Projection (MP)
- Median Breast Radius (MR)
- Lateral Breast Radius (LR)
- Inferior Breast Radius (IR)
Tools Needed:
- A measuring tape (or a ruler)
- A notebook
- A pen
- Wall mirror (for self-measurement)
How to Measure Your Breasts:
Step 1: Prepare for Measurement
First up, find a comfy spot where you can either sit or stand relaxed. Make sure the breast you’re measuring is, well, ready to be measured. It’s like preparing for a little self-care moment.
Step 2: Locate Your Nipple
This part’s easy. Your nipple is the small, raised center of your breast. Remember, it’s different from the areola, which is the surrounding area.
Step 3: Measure
Imagine a line starting from the center of your nipple. This will be your guide for the measurements. Now, the detailed steps:
1. MP – mammary projection
- Hold your breath to maintain a consistent chest position.
- Use a flexible tape measure under your breasts, right where they meet your chest.
- Lift your breast gently, put the tape at the crease beneath, and stretch it to the nipple’s center. This number is your MP.
- Repeat for the other breast.
2. MR – medial breast radius:
- Measure from the center of your chest to the inner edge of your breast, closest to your sternum (breastbone).
- Record this number and repeat for the other breast.
3. LR – lateral breast radius:
- This time, measure from your nipple to the outer edge of your breast, towards your armpit.
- Ensure the tape follows the natural curve of your breast.
- Note this measurement and do the same for the other breast.
4. IR – inferior breast radius:
- Measure from your nipple to where your breast meets your chest wall at the bottom.
- Follow the natural curve of your breast with the tape.
- Record this measurement and repeat for the other side.
Please ensure that the breasts are measured following the natural curve of your breast.
Step 4: Document Everything
Jot down all these measurements somewhere safe – could be in a diary or on your phone.
2. Archimedes (displacement of water) method
- Preparation: You’ll want a big container that can comfortably fit the breast without any spills. This container should be placed in a larger tray.
- Measuring Water Displacement:
- Fill the container with water right to the brim.
- Carefully submerge your breast into the water. It’s important to do this without spilling any water.
- The water that overflows from the container is collected in the tray or secondary container.
- Volume Calculation:
- To figure out the submerged breast volume, simply pour the overflowed water into a measuring jug.
In simpler terms, think of it like this: when you put your breast into the water, it pushes out an amount of water. The amount of water that gets pushed out is basically how much space your breast takes up. That’s your breast volume!
3. Imaging (mammography)
This is an approach more commonly seen in clinical or medical research settings. Here’s how it works:
- Mammography Imaging:
- Mammography is mostly for breast cancer screening, but it also gives us detailed breast pics.
- Your breast gets squished gently between two plates, and then X-rays are taken.
- Volume Calculation:
- Using these images, medical professionals or researchers can calculate the breast’s volume.
- This might involve using specific software or algorithms that can analyze the images and estimate the volume based on the breast tissue’s density and spread shown in the mammogram.
- Precision and Purpose:
- This method is quite precise and is useful in contexts where exact measurements are necessary, such as for surgical planning or treatment evaluation in breast cancer care.
Mammography involves exposure to a small amount of radiation and is typically used for health screenings rather than casual measurement of breast volume.
In a nutshell, think of it as a high-tech way to peek inside and measure the volume of the breast with great accuracy, mostly used by healthcare professionals for very specific reasons.
4. Grossman-Roudner device method
The Grossman-Roudner device is a tool specifically designed for measuring breast volume. Here’s how it is used:
- Design of the Device: The Grossman-Roudner device is cup-shaped and is designed to fit over the breast. It comes in different sizes to accommodate different breast sizes.
- How It Works:
- The device is placed over the breast, and it gently suctions the breast into the cup.
- When your breast is cozy and sealed, the cup’s volume is measured.
- Use in Clinical Settings:
- The Grossman-Roudner Device is typically used in clinical settings, such as plastic surgery consultations, especially for procedures like breast augmentation or reduction.
- Advantages:
- This method is non-invasive and can provide a direct and physical measurement of breast volume.
- It is more cost-effective than using casting and MRI, and is also more accurate than other methods like water displacement, especially in a clinical setting.
In a nutshell, the Grossman-Roudner Device is like a specialized fitting tool that carefully measures the volume of the breast.
5. Casting
So, here’s how they usually do the breast volume measurement, using a hands-on casting method:
- Preparation:
- The process starts with preparing the area and ensuring the person is comfortable. It’s important to protect the skin and surrounding areas from the casting material.
- Applying the Casting Material:
- A plaster or similar material is applied over the breast to create a mold. This material will capture the shape and size of the breast.
- The material is allowed to set and harden, forming a cast that is a replica of the breast’s outer shape and size.
- Removal and Measurement:
- Once the cast is set and removed, it can be filled with a liquid, usually water, to measure the volume.
- The amount of water it takes to fill the cast gives an accurate measurement of the breast’s external volume.
- Advantages and Considerations:
- The casting method is very accurate in capturing the external volume and shape of the breast.
- But, it takes more time and effort compared to other methods.
In simple terms, the casting method is like sculpting your breast for an ultra-precise size measurement.
6. Biostereometrics
Here’s how the biostereometrics method measures breast volume in a friendly way:
- 3D imaging:
- It uses cool 3D tech to take detailed pictures of the breast from different angles.
- Think of it like creating a 3D model of the breast’s surface using cameras or scanners.
- Data Analysis:
- Specialized software crunches the 3D pics to figure out the breast’s volume.
- It’s like capturing all the curves and shapes, so it’s super accurate.
- Why It’s Great:
- No touching or poking; it’s comfy for patients.
- It’s a fancy 3D snapshot of the breast, giving docs tons of info.
- It’s like tech meets healthcare, showing the body’s details with precision
In essence, biostereometrics is a blend of advanced technology and healthcare, offering a window into the body’s dimensions with remarkable accuracy.
Now that we’ve got the first part done, which is the volume, let’s dive into the next step: checking your breast tissue density.
Once you know that, calculating your breast weight is a breeze. Just multiply your volume (cubic cm) by the density (per cubic cm), and you’re good to go!
How to Calculate Your Breast Tissue Density for Accurate Weight Results?
Breast density, measured from mammograms, tells us how much dense tissue (like glands and fibers) is in your breast compared to fatty tissue. Here’s how it’s usually figured out:
- BI-RADS Categories:
- Radiologists use these categories to rate your breast density based on mammogram pics.
- It goes from 1 (mostly fatty, low-density) to 4 (really dense).
- The radiologist eyeballs the dense part’s percentage and picks a category.
- Automated Software:
- Some places have fancy software that calculates it automatically.
- The software looks at the mammogram and gives a percentage.
- This percentage shows how much dense stuff is there compared to everything else.
If you want to know your breast density and what it means for screening, chat with your healthcare provider or radiologist. They’ll give you personalized advice based on your unique breast health.
Understanding Breast Weight and Health
Let’s talk about breast weight and health in an extra-friendly way:
🌸 Breast Weight Variety:
- Breasts differ in weight due to genes, age, hormones, and body type.
- They’re made up of glands, fat, and connective stuff, and this mix affects their weight.
- Life stages like puberty, pregnancy, and menopause can change breast size and weight.
🏥 Why Breast Health Matters:
- Keeping your breasts healthy is a big deal; they can face various issues like cysts, fibroadenomas, and breast cancer.
- Self-checks and check-ups with your doctor are vital to spot any changes early.
