Finding the right size for anything we wear can be difficult at times, but shopping for period pants doesn't have to be. No need to worry about keeping track of which size you need from one store to the next when it comes to our period underwear.
Our period underwear size guide helps you find the correct size of Bodyform™ period pants for you so that you can feel comfortable and prepared for whatever your flow may bring.
Which size of period pants do I need?
If you've never used period pants before, it can be hard to know where to start. Luckily, there are a few ways to work out which size you need, some of which you may already use when shopping for normal underwear.
- Your hip measurement (this is the method we recommend)
- Your waist measurement (your natural waistline is the measurement around the middle of your torso - between your rib cage and hips)
- Go off your normal UK clothing size
| Size | Hips (inch) | Hips (cm) |
UK dress size |
|---|---|---|---|
| 2XS | 30-32 | 76-81 | 4 |
| XS | 33-35 | 84-89 | 6 |
| S | 36-38 | 91-97 | 8 |
| M | 39-41 | 99-104 | 10-12 |
| L | 42-44 | 107-112 | 14-16 |
| XL | 45-47 | 114-119 | 18-20 |
| 2XL | 48-50 | 122-127 | 20 |
| 3XL | 51-53 | 130-135 | 22 |
How to measure your hip size for period underwear
The hips are the joints on either side of your pelvis, below your waist and above your thighs.
To measure your hip size correctly, all you need to do is measure the circumference (the distance around your hips) at their widest point with a tape measure. To find the widest point, feel for the bones on each side. Using our handy size chart above, find the right size according to that measurement.
How do I know if I have the right fit?
Period pants are designed to have a slightly more snug fit than regular underwear, so any flows stay precisely where they should be all day. So don't worry if they feel a bit tighter than what you're used to. This just means you've found your perfect fit.
Your period underwear should be tight enough to your body to offer complete protection but not so tight that you feel uncomfortable. Your period pants should go unnoticed just like your regular underwear, so if they don't feel quite right, you could always opt for a larger size.
Bodyform™ offers a range of absorbency levels, from light flow all the way to heavy flow. So, combined with your perfect fit, you'll stay protected and comfortable all day.
How do I find the right size for teen period pants?
We understand that teenage bodies are unique and constantly changing, which is why our Teen Period Pants range has its own dedicated size guide. Unlike standard sizing, these products are specifically tailored to fit younger bodies, using measurements and fits designed with teens in mind.
Our teen sizes are based on height and age, rather than just waist and hip measurements, to provide the best fit for growing and changing bodies.
