Measure your natural waist right above your belly button, then find that number on the chart. Most of our trainers share one chart, with a separate column for the 12" Long because it is cut about 1" smaller; Luxx Hourglass, Invisible Zip & Clip, Hide The Back Fat latex-free and the men's trainers fit differently and have their own. Our sizes run from 3XS to 3XL.

Size is one of two choices. The other is height: 8", 10" or 12", which comes from your torso length, not your waist. The torso length guide covers that in two minutes.

Women's waist trainer size chart

One chart covers all three lengths (8", 10" and 12") of Active Sculpt, Active Sculpt Designs, Daily Sculpt, Neoprene Sweat & Sculpt, Triple Compression and the latex Hide The Back Fat. Your waist picks the size. Your torso length picks 8", 10" or 12". The 12" Long is cut a bit smaller, so in 12" each size fits a waist about 1" smaller: use the 12" column.

No tape measure? Your usual US size is a good starting point. The tape is still more accurate, because clothing sizes vary by brand. Not every line comes in every size: Active Sculpt Designs goes from 3XS to 2XL, and Neoprene starts at 2XS. The size picker on each product page only shows the sizes we make.

Luxx Hourglass size chart

Luxx Hourglass is our latex-free powernet trainer. Its chart lists your hips too. Go by your waist first, and use the hip number as a tiebreaker if your waist sits between two sizes.

Hide The Back Fat latex-free size chart

The latex-free version of Hide The Back Fat has its own chart. Its numbers are smaller than the women's chart, so your size letter will often be bigger than usual. Trust the chart, not the size you normally buy.

Men's size chart

Used for the Men's V-Taper and Men's Neoprene. Measure around your navel. If you measure 1.5 inches or more above a listed size, go up one. The pant size column is a guide only: if your stomach measures bigger than your pant size, go up a size.

Between two sizes?

  • First trainer: go up one size. A new trainer is stiff, and the bigger size is easier to hook while you get used to it.
  • Worn one before: go down one size for a firmer hold.
  • Invisible Zip & Clip: this one runs small, so order one size up from the chart either way.

Fit is personal, and customers land on both sides. Some size down after their first trainer. What size waist trainer should I get? goes deeper on choosing between two sizes.

“Comfortable and fits great. It does not move, but found that I could go down a size so I ordered a Small the next day.”

What if I'm outside the chart?

Our smallest size is 3XS and our largest is 3XL. If your waist is outside a chart, choose the closest size. Above the largest size, it will feel firmer than usual, so start on the loosest row of hooks and build up slowly. Below the smallest size, it will fit a little looser than intended.

Not sure which trainer you want yet? The comparison of all our trainers puts lengths, sizes and hold side by side.

If your size is wrong

All sales are final, but we exchange sizes. Request an exchange within 24 hours of delivery and send the item back within 7 days. Your first exchange is free. The trainer must be unworn and unwashed with tags attached, so try it on gently before you wear it out. Full details are in exchanges and returns.

Do your sizes run small?

Most of our trainers fit to their chart, so order by your measurement rather than your usual clothing size. The exception is Invisible Zip & Clip, which runs small: order one size up.

What if I'm outside the chart?

Choose the closest size we make. Our largest size is 3XL (a 41" to 44" waist on the women's chart). Start on the loosest hooks and build up slowly.

Is the size the same across all lines?

For most of them, yes. Active Sculpt, Daily Sculpt, Neoprene, Triple Compression and latex Hide The Back Fat share one chart. The 12" Long is cut a bit smaller, so in 12" each size fits a waist about 1" smaller. Luxx Hourglass, Invisible Zip & Clip, Hide The Back Fat latex-free and the men's trainers each have their own.

Can I go by my usual clothing size?

It's a good starting point. The women's chart lists the usual US size for each trainer size, and the men's chart lists pant sizes. Clothing sizes vary by brand, so if you can, measure: the tape measure wins.

Can the quiz pick my size for me?

Yes. The Find My Fit quiz asks for your waist, torso length and whether you've worn a trainer before, then picks the trainer, length and size.
