A faja size guide works by matching your real waist, hip, and torso measurements — not your regular clothing size — against the brand's specific size chart, since compression garments are built on their own sizing logic.
Getting this step right matters more than picking a favorite color or style: a faja that runs too small will roll, dig in, and cut off circulation, while one that runs too large won't give you the support you're paying for. Here's how to measure yourself correctly at home and avoid the most common sizing mistakes.
What Measurements Do You Need to Find Your Faja Size?
Most faja size charts ask for three numbers: your natural waist (the narrowest point, usually just above your belly button), your hip circumference (the widest point around your hips and glutes), and sometimes your torso length for full-body styles. Some post-surgical styles also ask for your bust measurement if the garment includes bust support.
| Measurement | Where to measure |
|---|---|
| Waist | Narrowest point of your torso, above the belly button |
| Hips | Widest point around your hips and glutes |
| Torso length | From underarm to hip crease, for full-body styles |
How to Measure Yourself Correctly at Home
Use a soft, flexible measuring tape, not a rigid one, and measure directly over your skin or a thin layer of clothing — never over bulky fabric. Stand naturally, breathe out normally, and keep the tape parallel to the floor without pulling it tight enough to compress your skin.
- Measure your natural waist first, standing relaxed.
- Measure your hips at their widest point, feet together.
- Write both numbers down and compare them to the size chart on the product page, not to your usual dress or pant size.
What If You're Between Two Sizes?
If your waist and hip measurements point to two different sizes, sizing up is usually the safer choice for comfort, especially for everyday wear or if this is your first faja. Sizing down can feel more dramatic at first, but it often leads to rolling, digging, and a garment that's harder to wear for long stretches.
The exception is post-surgical compression, where your surgeon's specific sizing instructions should always take priority over a general rule like this one.
Common Sizing Mistakes to Avoid
- Using your regular clothing size instead of your actual measurements — faja sizing almost never lines up with jeans or dress sizes.
- Measuring over thick clothing, which adds inches that throw off the whole chart.
- Assuming every style fits the same — a bodysuit, a short, and a waist cincher from the same brand can each have slightly different proportions.
- Ignoring torso length on full-body styles, which affects comfort as much as waist and hip measurements do.
Taking five extra minutes to measure correctly the first time saves you the hassle of an exchange later, and it's the difference between a faja that shapes comfortably and one that fights you all day.
Quick Tips for a More Accurate Measurement
A few small habits make your measurements far more reliable, whether it's your first faja or your fifth.
- Measure at the same time of day you'd normally wear the faja, since waist size can shift slightly morning to evening.
- Ask someone to help if you can — it's hard to keep the tape level and read the numbers accurately on your own.
- Re-measure every year or after a body change, such as pregnancy, surgery, or a significant change in weight, instead of assuming your size stayed the same.
- Check each product's specific chart rather than relying on a size you wore in a different style, since fit can vary from one garment to the next.

Frequently Asked Questions
What is the correct way to measure for a faja?
Measure your natural waist at its narrowest point and your hips at their widest point using a soft measuring tape, standing relaxed with the tape parallel to the floor, then compare those numbers to the specific product's size chart rather than your regular clothing size.
Should I size up or down if I'm between two sizes?
For everyday shapewear, sizing up is generally more comfortable and easier to wear for long periods, while sizing down can restrict movement and cause rolling; post-surgical garments should always follow your surgeon's specific sizing guidance instead.
Does faja sizing match my regular clothing size?
No. Faja sizing is based on your actual waist and hip measurements in inches or centimeters, and it rarely lines up with your usual jeans or dress size, so always check the specific size chart before ordering.
Can I exchange my faja if I order the wrong size?
Most orders can be exchanged within 30 calendar days of delivery as long as the garment is unworn and in its original condition — check the exchange policy on your order confirmation for full details.
