Size and fit

Choosing the right size

Measure according to body type. If belly is larger than hips: Measure at the same angle you wear your pants, from the small of your back to a point 3"- 4" below your navel. For men, this will be your pant size. If waist is smaller than hips: Measure at your waistline.

Size Measurement Men's Pant Size
XS 23"- 27" 24, 26
SM 27"- 31" 28, 30
MED 31"- 35" 32, 34
LG 35"- 40" 36, 38, 40
XL 39"- 44" 40, 42, 44
2X 43"- 48" 44, 46, 48
3X (ZZ) 48"- 52" 48, 50, 52

I am in-between sizes. Which size should I get?

If you are in-between sizes, either size will fit. However, most folks size down to avoid having to contend with greater fabric overlap in the front and a longer secondary strap. If your weight fluctuates up and down, it's better to size up.

Does Back-A-Line fit every body?


Back-A-Line belts were originally designed for male anatomy and reliably fit most men. The belt can also be used by women with a stocky build, an "apple-shape" body type or who are pregnant. Back-A-Line belts do not fit curvy or "pear-shape" women. (We're working on a solution!)

Those with spinal anomalies may not be able to use the belt. Back-A-Line's anatomic lumbar pad trains your back to assume a neutral lumbar lordosis. In order to be effective, your spine must be flexible enough to shape itself to the lumbar pad. If your spinal is inflexible or has a structural deformity, the Back-A-Line may be uncomfortable and ineffective. There is no harm in trying. It cannot hurt you. The worst thing that can happen is that it may not help. 

If you are not sure of the fit, remember that Back-A-Line offers a 30-Day Satisfaction Guarantee. So go ahead and give it a try!

Why does the XXX-Large (3X) size have no secondary cinch strap?

A secondary cinch strap on an XXX-Large Back-A-Line belt would be 54" long. A strap that long would be difficult to fasten. If left unfastened, such a long strap could because a tripping hazard.
