Learn how to measure your band and cup size at home with simple steps, so you can confidently order an EBY bra that fits comfortably all day.
Quick answer
To measure your EBY bra size at home, wear an unpadded bra or go braless, then use a soft tape measure. Measure your band size snugly around your ribcage, just under your bust. Measure your bust at the fullest point. Subtract band from bust to find your cup size. Write down both numbers and compare to EBY's size chart.
Finding a bra that fits well starts with knowing your measurements. If you're shopping for an EBY bra online, you can't try it on in a fitting room, but you can get a very accurate size at home with just a tape measure and a few minutes. This guide walks you through each step, with checkpoints to avoid common mistakes.
EBY bras are designed to be comfortable and supportive, but the right fit depends on accurate measurements. Whether you're looking at a Pain Free T-Shirt Bra or a sheer bralette, getting your band and cup size right is the key to all-day comfort. Let's go through the process step by step.
Before you start: what you'll need
You'll need a soft measuring tape, a mirror, and a notepad or phone to record numbers. Wear a non-padded bra or no bra at all. If you have a helper, even better, but you can do it alone. Stand in front of a mirror to keep the tape level and parallel to the floor.
Take your measurements in inches, as EBY's size chart uses inches. If you only have a centimeter tape, convert by dividing by 2.54. For the most accurate bra sizing at home, measure yourself at the end of the day when your body is at its natural size, not first thing in the morning.
- Use a soft tape, not a metal one, for comfort and accuracy.
- Keep the tape snug but not tight; it should not indent your skin.
- Write down each measurement immediately to avoid confusion.
Step 1: Measure your band size
Wrap the tape around your ribcage, directly under your bust. The tape should be level all the way around and snug against your body. Breathe normally and exhale before checking the number. This is your underbust measurement. Round to the nearest whole inch. If you get an odd number, round down to the nearest even number to find your band size.
Common mistake: pulling the tape too tight or letting it sag in the back. Check in the mirror that the tape is straight across your back. If you're between sizes, try the smaller band size if you prefer a snug fit, or the larger if you want more breathing room.
- If your underbust is 31 inches, round down to 30 for band size.
- For a snug fit, some prefer to go down a band size; for comfort, go up.
- Write down the number; you'll use it in the next step.
Step 2: Measure your bust size
Wrap the tape around the fullest part of your bust, usually across the nipple line. Keep the tape level and not too tight. You should be able to slip a finger under the tape. Stand straight and relax your arms at your sides. This is your bust measurement. Round to the nearest whole inch.
Common mistake: measuring over a padded bra or pushing the tape down. That gives an inaccurate number. If you have asymmetry, measure the fuller side and note it; you can adjust with removable pads if the bra allows.
- Wear a non-padded bra or no bra for this step.
- Keep the tape parallel to the floor; check in the mirror.
- Record the number immediately.
Step 3: Calculate your cup size
Subtract your band size from your bust size. The difference in inches determines your cup size. A 1-inch difference is an A cup, 2 inches is a B cup, 3 inches is a C cup, 4 inches is a D cup, and so on. For example, if your band is 34 and your bust is 37, you're a 34C.
Common mistake: using your underbust measurement instead of your band size. Remember, band size is your underbust rounded to the nearest even number. If you're unsure, double-check your math. EBY's size chart can confirm your cup size based on your numbers.
- Difference of 1 inch = A cup, 2 inches = B cup, 3 inches = C cup, 4 inches = D cup.
- If the difference is a half inch, round up to the next cup size for more comfort.
- Write down your final band and cup size together, like 34C.
Step 4: Check the fit with EBY's size chart
Now that you have your measurements, compare them to the size chart on each EBY product page. EBY bras come in various styles, and some may fit differently. For instance, the Raindrop Pain Free T-Shirt Bra uses SmartSilicone TecĀ® instead of an underwire, so it may feel different from a traditional bra. Check the specific product's sizing notes.

If you're between sizes, consider the fabric and support level. Bralettes like the Berry Milkshake Lucy Bralette are made from breathable mesh and offer soft, natural shaping, so they may be more forgiving. For a more supportive fit, the Nude Boob Job Bra has seamless construction and removable pads, and larger cup sizes provide extra support with wider straps and more coverage.
- Read the product description for fit notes; some styles run differently.
- When in doubt, size up for comfort in wireless styles.
- Check the return policy in case you need to exchange.
Step 5: Re-measure to confirm
For the most accurate bra size, measure yourself twice. Do the band and bust measurements again, and see if you get the same numbers. If they differ by more than half an inch, take an average or measure a third time. Consistency matters, especially if you're ordering online.
Common mistake: rushing and not keeping the tape level. Take your time. If you're still unsure, many EBY bras have adjustable straps and hook-and-eye closures that let you fine-tune the fit. But starting with accurate measurements saves you time and returns.
- Measure at the same time of day for consistency.
- If numbers vary, go with the larger band for comfort.
- Keep your measurements saved for future orders.
Your at-home bra measurement checklist
- Gather your tools: Soft tape measure, mirror, notepad. Wear a non-padded bra or go braless. Checkpoint: tape is soft and flexible, not metal.
- Measure your band: Wrap tape snugly around your ribcage under your bust. Keep it level. Round down to the nearest even number. Checkpoint: tape is parallel to the floor in the back.
- Measure your bust: Wrap tape around the fullest part of your bust. Keep it level and not too tight. Checkpoint: you can slip a finger under the tape.
- Calculate cup size: Subtract band from bust. 1 inch = A, 2 = B, 3 = C, 4 = D, and so on. Checkpoint: use band size, not underbust, in the subtraction.
- Confirm with EBY size chart: Compare your numbers to the size chart on the product page. Note any style-specific fit advice. Checkpoint: read product descriptions for fit notes.
- Re-measure to verify: Repeat steps 2 and 3. If numbers differ, average them or measure again. Checkpoint: consistent numbers mean you're ready to order.
