Trilogy One of a Kind Engagement Ring
Measure at home with confidence — printable sizer or your existing ring.
How to measure
Use an existing ring
Match the inside of your ring to the closest circle on the printable guide. The circle should sit inside the ring with minimal white showing.
Use the finger sizer strip
Print at 100% scale on US Letter. Cut out the strip, cut the slit, wrap it around your finger with numbers visible, and read the number closest to the opening. Slide it over your knuckle and choose a size that feels comfortable.
Quick fit tips
- Measure at the end of the day (fingers are slightly larger).
- Avoid measuring when hands are cold.
- If you’re between sizes, go up for comfort.
- Wide bands can feel tighter — consider +0.5 size.

FAQ
What if I’m buying a surprise gift?
If you can borrow one of their rings, measure the inside diameter. If unsure, pick a common size and we can guide resizing later.
Should I size up for thicker bands?
Often yes — thicker bands feel tighter. If you’re near the top end of a size, go up by 0.5.
Can you help me confirm my size?
Yes — send us your measurement (mm) or a photo of the printed sizer on your finger and we’ll confirm.
