How to Measure Your Bra Size at Home: Step-by-Step Guide for Full Busts

Finding a bra that truly fits is hard—especially if you have a full bust. A proper fit means no digging, no slipping, no gapping. But to get there, you need to know your accurate bra size—not just guess based on old bras or standard sizing.

This step-by-step guide will walk you through how to measure your bra size at home, using only a soft measuring tape and a mirror. No guesswork, just results.

Why Getting the Right Fit Matters

A wrong-size bra can lead to:

• Shoulder, back, and neck pain
• Unflattering shape under clothes
• Gaping cups or band ride-up
• Constant adjusting throughout the day

For full-busted women, these problems are amplified. The good news? It all starts with proper measurement.

What You’ll Need

• A soft tape measure
• A mirror
• A non-padded bra or no bra
• A notepad or phone to jot numbers down

Step 1: Measure Your Band Size

1. Stand in front of a mirror.

2. Wrap the measuring tape around your ribcage, just under your bust.

3. Make sure the tape is snug but not tight, and level all the way around.

4. Round to the nearest whole number.
   • If it's an even number, that’s your band size.

   • If it’s odd, round up to the next even number (e.g., 35 → 36).

Example: Ribcage = 33” → Band size = 34

Step 2: Measure Your Bust Size

1. Wrap the tape around the fullest part of your bust, across your nipples.

2. Make sure it’s relaxed—not tight—and level across your back.

3. Round to the nearest whole number.

Example: Bust = 40”

Step 3: Calculate Your Cup Size

Subtract your band size from your bust measurement:

• 1" difference = A cup
• 2" = B cup
• 3" = C cup
• 4" = D cup
• 5" = DD/E
• 6" = DDD/F
• 7" = G, and so on

Example: 40" (bust) – 34" (band) = 6" → Cup size = DDD/F

Final size = 34DDD

If you’re shopping for the STARLINA wireless bra, here’s what to keep in mind:

• Our bras are available in letter sizes (M, L, XL, etc.) with a detailed size chart based on bust and band measurements.
• If you’re between sizes, we recommend sizing up for more comfort.
• Designed especially for women with large busts, STARLINA bras offer full support without wires, wide straps, and seamless cups.

Tips for the Best Fit

• Re-measure every 6–12 months, especially if your weight, hormones, or lifestyle have changed.
• Try your bra on using the loosest hook—this gives you room to adjust as it stretches.
• The band should be snug, the straps supportive (not carrying all the weight), and the cups fully encapsulate your breasts.
