Measure a ring that fits

How it works

You need a ring that fits, a plastic card and a table. It takes about a minute.

A plastic card at the top of the table, a ring lying flat in the middle, and the phone above both.

1. Lay the ring and a plastic card flat on a table.
2. Hold your phone flat, about 25 cm (10 in) above them.
3. Hold still. You then get Halo sizes to try in your free kit.

Which rings work, and more tips

Choose a plain, round, solid ring that you wear now and that fits comfortably.

Please don't use a ring with a stone or setting on the inside, a signet ring, an oval or shaped ring, an adjustable, open or stretchy ring, a silicone ring, or a thumb ring.

• Lay a plastic card above the ring. The top of the picture is best.
• Use both hands to keep your phone steady.
• Or ask someone to hold the phone for you.
• A dark or mid-toned surface that isn't shiny works best.

How it works

You need a plastic card and a table. It takes about a minute.

A card at the top of the table, your hand flat below it, and your phone held level above both.

1. Lay the card flat on a table, with your hand below it.
2. Hold your phone flat above them, with your elbow on the table.
3. Hold still. You then get Halo sizes to try in your free kit.

More tips

An elbow resting on the table, the forearm leaning up, and a phone held flat above the table.

• Rest your elbow on the table to keep your phone still.
• Choose a plain, non-glossy surface in a contrasting colour.
• Rings off, and not straight after exercise, a hot shower or a salty meal.
• Or ask someone to hold the phone for you.
