Bratabase help » How to measure a bra
Depending on which bra your are about to measure you will be asked for any of these measurements:
- Bust perimeter
- Stretched band length
- Band length
- Cup width
- Cup depth
- Wire length
- Center gore height
- Side wing height
- Cup separation
- Strap width
We recommend to have a flexible tape measure handy or a string and a ruler to take the measurements.
If you don't have a measuring tape handy, you can use a string and a ruler. Use the string to mark distances and then measure them with your ruler
The bust perimeter is the measurement we are all used to take
This is when wearing the bra, across the fullest part of the cups with the tape parallel to the floor.
You will be asked for this measurement mostly on bras that don't have separate or defined cups, like compression sport bras and some swimwear.
Measure the length of the bra along the band, from hook to hook. Take the measurement from the endmost row of hooks to the other end of the bra with the hook.
Lay your bra on a flat surface in a natural shape and measure the distance of the band at rest.
Stretched band length
This is an optional measurement, as some of you may not feel comfortable doing this. That's OK.
Measure the the maximum length of the stretched band of your bra. This is useful to compare the elasticity of bras and helps recommending better fitting bras.
You can do this by grabbing one end of the measuring tape and one end of the bra with your clumsy hand and while holding the measuring tape with your strong hand pull the other bra's end and see on which number it stops.
Don't pull too hard as to deform or stretch the underwires.
Another way to do this, is by laying the measuring tape straight on the floor and stretch your bra along with it and check how far it reaches.
This is an imaginary straight line from tip to tip of the cup or underwire. For bras without underwire, measure from tip to tip of the cup.
Depending on the shape of the cup this measurement can vary a bit on the angle, as shown in the examples.
For this measurement do not include the width of the wires.
The depth of the cup is measure on the inside of the cup, from each end of the underwire (or where it should be located) across the deepest line of the cup.
TIP: If your bra has a soft fabric cup and if the size allows it, you can use your knee to fill the cup and measure across, in cups with thin materials it does not make an important difference if the measurement is inside or outside.
Remember that the ends of the measurement should be the same you used for the cup width, but this will always be a bigger measurement as this is the curve of the inside of the cup.
If your bra comes with removable padding, please remove it to take this measurement.
Measure the length of the wire across the cup border from end to end.
We are measuring the actual size of the underwire NOT the wire channel which could have extra empty fabric.
When the bra is at rest, measure the distance at the closest point of the cups making sure that the center gore is not deformed.
This measurement will be useful to look for bras for breasts that are closer or separate to each other.
Center gore height
This is the height of the bra's center gore, the center gore is the piece of fabric where the cups meet at the center. Its height goes from the highest point to the bottom of the fabric.
Side wing height
This measurements refers to the height of the band where it meets the cup.
Measure how wide the bra strap is. If it varies, measure at shoulder level.
The number of hooks that you need to close to close the bra in one row.
