You can download our printable ring sizer for measuring your ring size at home.

Make sure your printer is set to 100-percent. Do not reduce the print size in your printer ‘page setup’ area. You can verify that the ring sizer printed correctly by measuring it with a ruler; it should measure 3 1/2 inches long from "A" to "B".

4. Tell A Fib

Just this one time, lie and pretend you're getting a relative a ring they like. Take your loved one with you, at that point request that they give it a shot in their size to 'see what it looks like'. Simply remember to listen out for their size.

5. Ask A Family Member

To confirm a 'secret' measurement, try asking her mother, or close friend if they know her ring size.

When you’re finding out your ring size, don’t forget these useful tips.

1. Don’t measure your finger when you are cold. Cold fingers are smaller, often by as much as half a size!

2. Our fingers are at their largest during the evening, so this is the best time to make a measurement.

3. For best results, measure the finger several times and choose the size that comes up most frequently.

4. If you are unsure about the ring size, buy a slightly larger ring, so it will fit over her finger at the right moment!
