How to Accurately Measure Your Bra Size: Step-by-Step Guide To Achieving The Best Fitting Bra
Take a look at our bra measuring chart for the best bra measuring help and advice.
The best way to check your bra size, you need two measurements underbust and overbust.
How to Measure Your Underbust Correctly for Accurate Band Size (Underbust Measurement - Back Size)
Ensuring your bra band fits correctly and comfortably is key to discovering your bra size, especially for plus-size women who need extra support. A question that comes up all the time when thinking about meauring is, "When measuring for a bra do you wear a bra?" We always recommend wearing your bra on the loosest hook to begin with. As the fabric gives over time, you can wear the bra on a tighter hook. If you find the bra straps are slipping off your shoulders, the band rides up your back, or you’re experiencing bulging or rubbing under your arms, this could be an indication that your band size is too big or too small.
Here's the best way to measure your band size:
- Using a soft tape measure, measure directly under your bust in inches, keeping it snug and level around your body.
- If the measurement is an even number, add 4 inches.
- If the measurement is an odd number, add 5 inches.
For example, if your measurement is 36 inches, add 4 inches for a 40 band size.
Sally says every daughter puts her mother in a bra that's too small, if you are sure you don't need to add the extra then don't, but if your bra is uncomfortable, especially at night, then please follow the guide in the first instance or give us a call on 01439 798388.
How to Measure Your Overbust Correctly for Accurate Cup Size (Overbust Measurement – Bust Size)
To achieve the best bra fit for larger busts, it’s important to measure your cup size correctly. A well-fitted cup should provide maximum support without spillage or gaping. We are often asked, "do you wear a bra when measuring bust?" We always recommend wearing your best fitting bra to measure your cup size - don’t do it without wearing a bra.
Here's the best way to measure your cup size:
- Make sure you’re wearing your best fitting bra.
- Using a soft tape measure, measure the fullest part of your bust, ensuring it's level around your body.
- If this measurement is 1 inch more than your underbust, your cup size is A.
- For every inch difference between your underbust and overbust, your cup size increases by one.
- An increase of 2 inches equals a B cup, 3 inches equals a C cup, and so on.
For example, if your underbust measures 29 inches and your bust measures 34 inches, that's an additional 5 inches, making you a DD cup size.
