How to use the Garment Trims Calculator (Buttons & Zips)

Trims are cheap per piece but ordering wrong stops the finishing line — and buttons are bought in gross, a unit nobody remembers. This how many buttons per shirt calculator takes your garment count and the buttons and zips per piece, then gives total buttons, the gross count for the supplier, and total zips. It is the five-second trim sheet for merchandisers and boutique owners placing accessory orders.

Formula

Total buttons = garments × buttons each. Gross = total ÷ 144 (1 gross = 144 pieces = 12 dozen). Total zips = garments × zips each. Example: 200 shirts × 7 buttons = 1,400 buttons = 9.72 gross → order 10 gross + spare.

Worked example

An order of 500 dress shirts with 7 buttons each: 3,500 buttons = 24.3 gross → order 25 gross plus 5% spare (26–27 gross). Trousers with 1 zip each: 500 zips. For 1,000 kurtas with 3 buttons each: 3,000 buttons = 20.8 gross → 21 gross plus spare.

Frequently asked questions

A standard dress shirt uses 7: five down the front placket, one on each cuff, plus manufacturers usually attach one spare. Kurta-style shirts with a half placket need 3–4.

144 pieces (12 dozen) — the wholesale trading unit for buttons worldwide. Suppliers quote per gross, so divide your total button count by 144 before ordering.

Add 3–5% over the calculated quantity for sewing-machine drops, QC rejects, and the spare button sewn into each garment. On small orders, round up to the next full gross.
