Tip for an accurate paper ring sizer
The small slit where the paper loops through itself is essential for the sizer to work properly. For best results, make a clean and narrow cut along the marked line.
You can use a precision cutter, or gently press with the tip of your scissors. Avoid making the slit too wide, a precise opening helps the strip slide through smoothly and ensures a more reliable measurement.
Frequently asked questions printing a ring sizer
When your knuckles are noticeably larger than the base of your finger, it’s best to take two separate measurements: one at the knuckle (A) and another at the base (B). If the difference is less than two sizes, go with the base size. The ring may need a bit of pressure to pass over the knuckle, but it will sit securely once in place. If the difference is greater, it’s better to choose a size in between, staying close to the base size to avoid the ring spinning. For engagement rings or valuable pieces, we recommend visiting a jeweler who can offer solutions like sizing beads, butterfly springs, or hinged shanks to ensure a secure and comfortable fit.
Yes, regular printer paper works fine. For better durability, you can use slightly thicker paper so the ring sizer holds its shape more easily.
If you don’t have a printer, you can use a strip of paper, string, or a measuring tape to measure your finger circumference and compare it to our size chart.
Finger size can fluctuate slightly throughout the day. For best results, measure your finger at the end of the day, when your hands are at their most natural size. Avoid measuring when your hands are cold, right after exercise, or just after waking up. To improve accuracy, you can measure at different times and use the most consistent result.
