What size are suit jacket buttons?

Most jackets use buttons around 3/4 inch (20mm) on the front and 5/8 inch (15mm) on the sleeves. Every set in this collection includes both sizes, four front buttons and twelve smaller ones, so you do not have to order twice.

Can I replace just one suit button?

You can if you find an exact match, but even a slight difference in color or sheen is visible on a jacket front. Replacing the full set is the safer route, and it is what most tailors do. Each set here covers the front and sleeves in one go.

Are horn buttons better than plastic suit buttons?

Different, more than better. Buffalo horn has natural grain, so each button is unique and the look is classic tailoring. Poly-nylon is tougher against scratches and keeps an even color across the set. Both handle regular dry cleaning without trouble.

How do I match new buttons to my suit?

Check the color against the fabric in daylight, not under indoor bulbs. If you are between shades, pick the darker one, it will blend where a lighter button would stand out. Black or dark navy works on the large majority of business suits.

Additional Information

Replacement suit buttons in the two sizes tailors actually use: larger buttons for the jacket front, smaller ones for the sleeves and trousers. Every set here includes both, sixteen buttons in total, so one order covers the whole suit and keeps the finish consistent from front to cuff. The range runs from basic poly-nylon sets in everyday colors to genuine buffalo horn buttons with natural grain, plus a vegan option that gives you the horn look without the horn. Colors cover the suits people actually own: black, navy, charcoal, browns and tans. A lost button is the usual reason people land here, but worn plastic buttons are the better one. Swapping in a full set of suit jacket buttons is the cheapest upgrade tailoring has to offer, and it takes one quiet evening with a needle and thread.
