How to measure a hoodie
Every point, drawn on the garment so there is no guessing where the tape goes.
Quick answer
Lay the hoodie flat and measure ten points: chest, length, shoulder, sleeve (upper and lower), arm, forearm, cuff, waist and hem, in fit-impact order. Chest leads, taken across the relaxed body an inch below the armhole, and the arm and forearm widths are the points most guides skip. Tap each step on the diagram to see where the tape sits.
Shoppers buying a pullover hoodie size on chest and length first, then on how the heavy sleeve sits on the arm. Ten points define that fit. Most listings give a chest, maybe a length, and skip the rest, which leaves the sleeve and cuff a coin toss on a bulky fleece. Here every point is drawn on the actual garment, sleeve widths included.
- A
Chest
The first number a buyer reads, taken straight across the body an inch below the armhole. Tap this step for the exact line. Hoodies carry extra ease for layering, so smooth the fleece flat instead of pulling it wide.Double it for the full chest circumference.
- B
Length
One vertical run from the high shoulder point, beside the hood seam, down to the ribbed hem. Tap the step to see where the line starts. Length tells a buyer whether the hoodie crops at the waist or drops past it.Recorded as-is. Do not double.
- C
Shoulder
Seam to seam across the back. Many hoodies use a dropped shoulder, so the seam sits down the arm and reads wide. Follow the real stitch line rather than the natural shoulder point.Recorded as-is. Do not double.
- D
Sleeve A
The upper sleeve run, from the shoulder seam toward the elbow. Splitting the sleeve in two keeps a long fleece sleeve from hiding inside one rounded number.Recorded as-is. Do not double.
- E
Sleeve B
The lower sleeve run, from where the upper sleeve ends to the ribbed cuff. With Sleeve A it gives the full reach a buyer feels at the wrist.Recorded as-is. Do not double.
- F
Cuff
Across the ribbed band at the wrist, measured relaxed. The rib stretches to pull on and recovers, so read it settled and let the diagram mark the exact span.Double it for the cuff circumference.
- G
Waist
Across the body at its narrowest point above the hem rib. A relaxed hoodie runs nearly straight here; a tapered cut pulls in, so the gap from chest to waist tells the shape.Double it for the full waist circumference.
- H
Hem
Across the ribbed bottom band, read relaxed. This band cinches the hoodie at the waist, so a buyer wants the resting width, not the rib stretched open.Double it for the full hem circumference.
- I
Arm
Across the widest part of the upper sleeve, near the armhole, where the bicep sits. Tap the step to see the line. On a fitted hoodie this width decides whether the arm feels snug or roomy.Double it for the full upper-arm circumference.
- J
Forearm
Across the lower sleeve, partway between the elbow and the cuff. This catches how the sleeve narrows down the arm, which a single sleeve length never shows.Double it for the full forearm circumference.
Measure flat and never stretched, letting the ribbed cuffs and hem settle to their resting size. The across measurements, chest, arm, forearm, cuff, waist and hem, each double to a body circumference; length, shoulder and the two sleeve runs stay as single passes. On thick fleece a relaxed reading is the only number a buyer can match at home.

Frequently asked
How do I measure a hoodie sleeve and arm width?
Lay the sleeve flat along its seam. Measure the upper run from the shoulder seam toward the elbow, the lower run from there to the cuff, then take the arm across the widest point near the armhole and the forearm across the narrower section below. The two length runs stay as measured; the arm and forearm widths double for the body circumference.
Should I measure a hoodie stretched or relaxed?
Relaxed, on a flat surface. Fleece and its ribbed trims give under tension, so a stretched reading reports a hoodie roomier than it wears. Smooth the garment without pulling, let the cuffs and hem rib settle, then read each point. That relaxed figure is what a buyer can repeat against a hoodie in their own closet.
Which hoodie measurements double and which stay as they are?
Double the across points: chest, arm, forearm, cuff, waist and hem, because each spans one flat layer and the body wraps both sides. Keep length, shoulder and the two sleeve runs exactly as measured, since each is a single pass along the garment. A 23 inch flat chest is roughly a 46 inch body circumference.
What size hoodie am I if my chest is 42 inches?
A 42 inch body chest commonly fits a medium to large in a relaxed pullover hoodie, near a 23 to 25 inch flat chest with layering ease built in. Size down for a trim fit or up for an oversized look. Hoodie cuts vary a lot between brands, so match the flat chest and length to a hoodie you already wear.
Should I list hoodie measurements in inches or centimeters?
List whichever your buyers use, but keep one unit per chart and label it. Sellers shipping across borders do best showing both, since one market reads inches and another centimeters. Sizely puts both units on every chart automatically. For regional sizing, see our men's international size chart.
