Multisizer

The Multisizer is a narrow plastic sizing strip that works in the same way as a jeweller’s ring gauge. One end feeds through a small buckle to create an adjustable loop. When you slide the loop onto your finger and pull the strip gently, the loop tightens until it sits where a ring would normally rest. The printed scale along the strip then shows your ring size directly.

The buckle holds the strip in position once it is tightened, so the loop does not loosen while you read the measurement. Because the plastic is thin and flexible, it sits close to the finger rather than standing away from the skin. This gives a feel that is closer to a real ring than thicker home sizing tools.

Each Multisizer we send out also includes a voucher code for the same value, which can be redeemed against any purchase. Many customers use the tool to confirm their size before ordering a ring, then apply the voucher when they place the order.

Multisizer ring sizing tool

How it works

The Multisizer arrives as a flat plastic strip with the buckle already fitted at one end. Once the loop is on your finger, pull the strip slowly so it closes around the finger.

The movement is similar to tightening a cable tie, but the strip can also be loosened again if you pull it back through the buckle. Rotate the loop gently over the knuckle and settle it at the base of the finger. When the loop feels secure but not tight, read the letter size shown on the printed scale.

The scale displays standard UK letter sizes, which correspond directly with the sizes used for rings in the UK. If you are measuring more than one finger, or checking sizes for more than one person, the strip can simply be loosened and used again.

Getting an accurate measurement

Finger size can vary slightly during the day, so it helps to measure when your hands are at a normal temperature. If the loop feels tight as it passes over the knuckle but loose once it is in position, try adjusting it a few times until the reading settles consistently.

If the first reading looks unexpected, measure again after a few minutes and compare the results. Repeating the measurement once or twice usually confirms the correct size.

It is also worth remembering that wider rings tend to feel tighter than narrow ones. If you are planning to order a broader band, the Ring Width Guide explains how width can influence the size that feels comfortable. There is also an interactive sizing tool that suggests the right size to order based on your Multisizer reading and the width of ring you are considering.

The voucher

Every Multisizer we send includes a voucher code for the same value as the tool. When you later order a ring or other item, the code can be applied at checkout. In practice this means the cost of the sizing tool is returned to you when you make a purchase.
