Faja size guide: how to choose the right size
A faja only works when the size is right. Too small and it digs in and rolls; too big and it won't shape. Here's how to get it right the first time.
1. Take two measurements
You only need a soft measuring tape and two minutes. Measure over bare skin or thin underwear, standing relaxed – don't pull the tape tight and don't hold your breath.
- Waist: the narrowest part of your torso, usually just above the belly button.
- Hips: the widest part of your hips and butt, with your feet together.
Your weight helps too, but measurements are more reliable because weight sits differently on every body.
2. Read the size chart
Fajas are sized by body measurements, not garment measurements. A firm-compression faja is made smaller than your body on purpose – that's how it shapes. Here is the chart we use for our full body shaper:
| Size | Weight | Waist | Hips |
|---|---|---|---|
| S | 115–130 lb | 23–27″ | 34–38″ |
| M | 130–148 lb | 27–30″ | 39–42″ |
| L | 148–165 lb | 30–32″ | 43–46″ |
| XL | 165–185 lb | 33–35″ | 47–49″ |
| 2XL | 185–205 lb | 36–38″ | 50–51″ |
| 3XL | 205–225 lb | 39–41″ | 52–54″ |

3. Between two sizes? Go up
If your waist says one size and your hips say another, choose the larger one. With firm compression, sizing down rarely gives a better shape – it just makes the faja harder to close and less comfortable to wear for more than an hour or two. The hooks let you tighten the waist as the garment relaxes.
4. How a faja should feel
- Right size: snug and firm, but you can breathe, sit and bend normally. The hooks close with a little effort on the outer row.
- Too small: you can't close the hooks, the leg bands dig in, or you feel numbness or pain. Take it off and size up.
- Too big: fabric wrinkles at the waist, straps slide, or the leg bands roll up.
New to compression? Start with a few hours a day and build up. A faja is not a medical device and does not cause weight loss – if you're wearing one after surgery, follow your doctor's instructions.
5. Putting it on the easy way
- Open all the hooks and step in, pulling the faja up to your waist.
- Slide your arms through the straps and adjust them to a comfortable level.
- Close the hooks from the bottom up on the outer row. Move to the inner row once the fabric relaxes after a few wears.
