Choosing the wrong faja size is the number one reason women are disappointed with their results. Too small and it is uncomfortable and rolls. Too large and it does not provide enough compression to work. In this complete faja size guide, we walk you through exactly how to measure yourself, how to read a faja size chart, and how to choose the perfect size for your body and your goals.
Why Faja Sizing Is Different from Your Clothing Size
This is the most important thing to understand: your faja size is not your clothing size. Colombian fajas are sized based on your body measurements — specifically your natural waist and hips — not the tag on your jeans or dress. A woman who wears a size 10 dress might wear a medium faja, a large, or an XL depending on her actual measurements. Always size from your measurements, never from your clothing size.
Step 1 — Take Your Measurements
You will need a soft measuring tape. Take these measurements:
- Natural waist: Measure around the narrowest part of your torso, usually 1–2 inches above your belly button. Stand naturally, do not suck in.
- Hips: Measure around the fullest part of your hips and glutes. Make sure the tape is level all the way around.
- Weight: Knowing your weight helps determine compression level needs.
Step 2 — Read the ImeBoBo Faja Size Chart
| Size | Waist (inches) | Hips (inches) |
|---|---|---|
| S (Small) | 25–27 | 35–37 |
| M (Medium) | 27–30 | 37–39 |
| L (Large) | 30–33 | 39–42 |
| XL (Extra Large) | 33–36 | 42–45 |
| 2XL (Double XL) | 36–40 | 45–49 |
Always use your largest measurement to determine your size. If your waist is a medium but your hips are a large, choose the large.
Step 3 — Decide Your Goal: Comfort or Maximum Compression?
- Size up for all-day comfort wear, first-time faja wearers, or postpartum use.
- True to size for daily shaping with balanced compression and comfort.
- Size down for maximum compression, experienced faja wearers, or waist training goals.
Common Faja Sizing Mistakes to Avoid
- Sizing by clothing size — Always use measurements, never clothing labels.
- Sizing too small — An overly tight faja rolls, digs, and cuts off circulation.
- Not accounting for your hips — Many women size for their waist and forget their hips.
- Ignoring torso length — If you are tall, check the torso length of the faja.
What If You Are Between Sizes?
- First time wearing a faja → go up one size for comfort
- Experienced faja wearer → stay true to size or go down one size
- Post-surgery recovery → follow your surgeon's recommendation
How to Know If Your Faja Fits Correctly
Your faja fits correctly when you can zip it closed without straining, you can breathe normally while wearing it, the waistband does not roll down, there are no red marks or indentations after wearing it for 1 hour, and you feel firm, even compression — not pain or pinching.
