Chest

Lift your arms slightly and measure around your body (without a shirt is best), crossing over the fullest part of your chest.

Neck

For casual shirts, find a collared shirt that fits your neck well. Lay the collar flat on a table and measure the ”top” edge of the collar. For dress shirts, measure around the base of your own neck, keeping one finger between your neck and the tape measure.

Sleeve

Place your hand on your hip with your arm bent at 90 degrees. Measure from the middle of the back of your neck, across the shoulder, and down your arm to the wrist.

Tall Fit Guide

Tired of sleeves that are too short? Want shirts that don't ride up whenever you raise your arms? You've come to the right place. Our tall styles collection features classic Gap styles, updated to fit you better than ever. We've simply adjusted the proportions with our tall-sized guys in mind. When buying tall styles, we recommend ordering your regular Gap size.
Regular Shirt vs. Tall Shirt
Our tall styles are for you if regular-sized shirts fit in the chest and shoulders, but the body length and sleeves are often too short.
Sizes M- XL: 2” longer in the body
Sizes XXL- XXXL: 1 ½” longer in the body
Long-sleeved styles: 1” longer in the arm than regular sized styles
Short-sleeved styles: ½” long in the arm than regular sized styles

Waist

Measure around your waist where your pants usually fall. Keep one finger between the tape and your body to ensure an accurate fit.
