Say goodbye to ill-fitting swimsuits with these measurement tips for plus size

Measuring your body is easy. Plus, you only need to measure yourself once in a while. Just jot down the measurements and use it as a reference when online shopping.


Double-check from time to time to see if there are any changes. All body measurements can fluctuate based on circumstances; this is completely natural.

If you're comfortable, ask someone you trust to help you so that you get the most accurate numbers. However, if you decide to do it yourself, take a deep breath and relax. All you need is about 5 minutes and you're all set.

These are the things you'll need:

  1. A full-length mirror

  2. 2 Fabric tape measures (or a long piece of string and a regular tape measure)

  3. A calculator

  4. A pen or pencil

  5. Paper


What should you wear while taking your measurements?

Ideally, you should wear a good-fitting, supportive bra with minimal or no padding and comfortable underwear. If you wear clothes while measuring, your numbers may not be correct.

Take your measurements twice to ensure they're accurate.

Measure the widest part of your bust for this measurement

Stand sideways and look at yourself in the mirror. Your bra back should be parallel and in line with the front of your bra and the ground. Now run the tape measure horizontally across the fullest part of your bust, ensuring it is still parallel to the floor.

Write down the number you get on your paper.


2. Measuring your underbust

You will need to measure under your bust for this measurement

Again, please make sure you wear a supportive bra that fits well as mentioned above. Stand sideways and look at yourself in the mirror. Your bra back should be parallel and in line with the front of your bra and the ground. Now run the tape measure horizontally just under the bottom of your bra at the back, ensuring it is still parallel to the floor.

You want to make sure the tape measure is sitting under your breasts and doesn’t include any of your busts. This is where the mirror comes in handy.

Write down the number you get on your paper.

3. Measuring your waist

You will need to measure your waist at its smallest point for this measurement. You will need to measure on bare skin. Stand in front of a full-length mirror and bend to one side, looking for the natural indentation in your torso. This is your natural waistline. If you cannot find your natural waistline, you can measure the lowest point of the rib cage, which is midway around your torso.

You will need to measure your stomach at its fullest point for this measurement.

Look in the mirror and position the measuring tape vertically at the side of your body. The tape measure should then be placed at the lowest edge of the string or ribbon. Measure approximately 10 cm down from the waistline or to the widest point of your tummy.

Having a friend is great to help with measuring your torso or body length. You will likely need both tape measures for this step.
