How to measure
Chest
Lay a tee flat and measure straight across, armpit to armpit, then double it. Or wrap a tape around the fullest part of your chest, staying level.
Length
From the highest point of the shoulder seam straight down to the bottom hem.
Shoulder
Seam to seam across the back, from the edge of one shoulder to the edge of the other.
Fit notes
Regular fit
Every 4KAY tee is cut regular fit — true to size, room to move, not baggy, not painted on.
Between sizes?
Size up. A slightly relaxed tee always beats a tight one after the first wash.
Still not sure?
Every product page has a size assistant — feed it your height and weight, it does the math and tells you exactly which size to pick.
