Compare, don’t guess
A fit check before you order.
Measure a comfortable pair and compare it with the candidate’s garment measurements. Body-size charts are not garment measurements and should not be entered as though they are.
The differences will appear here.
Enter at least one complete measurement pair. The tool compares dimensions; it does not predict a size or guarantee fit.
Keep the comparison meaningful
Use flat garment measurements on both sides. A 16-inch flat waist is not a 16-inch waist circumference. The tool doubles only the difference between flat waist widths when explaining the approximate change around the waistband.
Measure the inseam from the crotch seam down the inner leg. For rise and thigh, follow a consistent measuring method and check the brand’s diagram where available. A different measurement location can make two numbers misleading.
Fabric stretch, waistband elasticity, cut and seam position still affect movement. Similar measurements do not prove that two pants will feel the same.
Read the movement-based fit checks or return to the pants finder.
