Wedding rings in large sizes: UK size Z and above

What counts as a large ring size in the UK?

There is no official line. The UK scale runs from A to Z and the last few letters, from about T upwards, sit towards its larger end. Z is the last letter: 68.8mm around the inside of the ring and 21.9mm across it, which is a US 12.75 and a European 69.

Anything above Z is large by any measure, because the letters have run out. If the rings in a shop's tray stop short of your finger, a ring made to order is the answer: it is made in your size from the start.

UK ring size Z: Z in US, European and millimetre sizes, with what a band weighs at that size.

What comes after Z in UK ring sizes?

Z½, then Z+1, Z+1½, Z+2 and so on, a half size at a time. The number counts on from Z, where the letters stop. Our size lists run this way up to Z+10.

Some charts leave out the plus sign and write Z1. On our rings Z½ is 69.4mm around the inside (a US 13), Z+1 is 70.1mm around and 22.3mm across and Z+10, the largest, is 81.2mm around and 25.85mm across.

Which men's wedding rings are made in large sizes?

Every titanium, black zirconium, anodised zirconium and inlay band we make. Each is made to order in every half size from A to Z, then in Z½ and from Z+1 to Z+10 in half sizes, at any width it comes in.

Our solid gold bands are made in whole sizes from A to Z. So a size Z wedding ring can be gold, titanium or zirconium. For a half size, or for anything above Z, choose titanium, black zirconium or an inlay band.

Titanium rings: The lightest bands we make, in sizes up to Z+10.

Black zirconium wedding bands: Black zirconium bands, in sizes up to Z+10.

Does a made-to-order ring cost more in a large size?

No. Every size is the same price: A to Z+10 on the titanium, zirconium and inlay bands and A to Z on the gold bands. A larger ring takes a little more metal and the price stays where it is.

Width is what can change the price. Each ring's page lists the price of every width it is made in.

Which metal and width suit a large finger?

A wider band, in titanium or black zirconium if you want it light. Broad fingers carry 7mm or 8mm well and long fingers can take 8mm to 10mm. A very fine band can look lost on a large hand.

Weight is where the metals differ. By our ring weight model, a plain 6mm band at UK size Z weighs about 2.7g in titanium, 4.0g in black zirconium and 6.9g in 9ct gold. At 8mm it is about 3.7g in titanium and 5.3g in black zirconium. Our titanium and zirconium bands are made from 4mm to 10mm wide and our gold bands from 2mm to 7mm.

6mm or 8mm?: How the two widths compare on the hand.

How do you measure a large finger for a ring?

Measure a ring that already fits that finger: its inside diameter in millimetres, straight across the centre. A ring that fits has already passed the knuckle, which for most people is larger than the rest of the finger.

Our ring size finder reads sizes up to Z, which is 21.9mm across or 68.8mm around. If your measurement is larger, keep the figure in millimetres and get in touch, or choose I do not know yet on the ring's page. We confirm the size with you before anything is made.

A wide band feels snugger than a narrow one at the same size, so measure with a ring about as wide as the one you are buying. Fingers shrink in the cold and swell in the heat, so measure at room temperature.

How should a wedding ring fit?: Snug but not tight and how to tell.

Finding a ring size secretly: For a ring bought as a surprise.

What happens if the size is wrong?

An unengraved ring that arrives the wrong size comes back within its returns window like anything else. An engraved ring cannot come back for a change of mind, so be sure of the size before you add an engraving.

Later on, the metal decides what can be done. A plain gold band can be made larger or smaller by a jeweller. Titanium can often be made slightly larger by machining the inside of the band, though never smaller. Black and anodised zirconium are not resized in the usual way, because the colour is grown into the surface, so on those the size is settled when you order.

Which rings can be resized: Resizing, metal by metal.
