Why Sizing Matters

The most common buyer complaint is getting the wrong size. This is avoidable. The USFans spreadsheet includes size charts for most items. You just need to know how to measure and compare.

How to Measure Yourself

Use a soft measuring tape. Do not use a metal ruler or a string. Measure while wearing thin clothing. Stand straight and relaxed. Write down each measurement.

Clothing Measurements

  • Chest: Measure under armpits, across the widest part
  • Shoulder: Measure from shoulder tip to shoulder tip
  • Length: Measure from back collar to hem
  • Sleeve: Measure from shoulder seam to cuff
  • Waist: Measure where you wear your pants
  • Inseam: Measure from crotch to ankle
  • Thigh: Measure the widest part of your thigh

Shoe Measurements

Measure your insole length in centimeters. Place your foot on a piece of paper. Mark the heel and the longest toe. Measure the distance. Compare with the spreadsheet size chart. Most shoes run 0.5-1 size large.

Step 4

Compare with the spreadsheet size chart. Add 0.5-1cm for comfort room.

How to Read the Spreadsheet Size Chart

The size chart shows the garment measurements, not the body measurements. A hoodie with a 60cm chest measurement means the hoodie is 60cm across. Your chest measurement should be smaller than the garment measurement for a comfortable fit.

Chart Tip

Add 2-4cm to your body measurement for a comfortable fit. For an oversized fit, add 6-10cm. For a fitted look, add 0-2cm.

What to Do If You Are Between Sizes

If you are between sizes, check the fabric type. Stretchy fabrics can accommodate a smaller size. Non-stretch fabrics need the larger size. When in doubt, size up for comfort.
