1.5 mm vs 2 mm Ring Engraving Characters: Which Size Should You Use?
Inside-ring engraving depends heavily on character size. This VEVOR manual engraver uses a double-sided character dial with 1.5 mm and 2 mm characters, so the main choice is how much usable inner-band height you have and how prominent you want the letters or numbers to appear.
1.5 mm or 2 mm — which ring engraving character size should you use?
Choose 1.5 mm when the ring has a narrower inner band or when you want more compact lettering. Choose 2 mm when the inner band has enough vertical space and you want larger, more prominent characters. Before engraving, measure the usable inner-band area and leave clearance from the ring edges.

| Character Size | Best Starting Point | Main Tradeoff |
|---|---|---|
| 1.5 mm | Narrower inner bands or compact inscriptions | Smaller, less visually dominant text |
| 2 mm | Wider inner bands with more vertical clearance | Needs more usable band height |
Measure the Usable Inner-Band Height First
Do not choose character size from ring diameter alone. The important measurement is the usable vertical area on the inside surface of the band where the characters will sit.
Measure the flat or engravable inner section and leave clearance from both edges. A band that technically measures 2 mm high may still be too tight for a 2 mm character if the edges are curved, beveled or rounded.
What the 80-Character Dial Gives You
The product lists an 80-character lettering plate with English letters and Arabic numerals. The double-sided dial provides the two character-size options: 1.5 mm and 2 mm.
Before starting a job, confirm that every required letter or number is present on the dial and plan the inscription length in advance. Character height and total inscription length are different constraints: a ring may have enough vertical height but still have limited circumference for a long message.
Ring Fit and Layout Checks
01 · Inner-band height
Make sure the selected character height leaves visible clearance above and below the engraving area.
02 · Band curvature
Highly rounded or contoured inner bands can reduce the flat area available for clean character placement.
03 · Inscription length
Long names, dates or messages need more circumference. Plan spacing before engraving the first character.
04 · Chuck fit
Confirm the ring can be securely centered and held in the self-centering chuck without unstable movement.
Quick Character-Size Checklist
- I measured the usable inner-band height, not just the ring size.
- I checked whether the inner surface is flat enough for the planned character height.
- I chose 1.5 mm for a more compact inscription or 2 mm for larger characters when space allows.
- I confirmed the required letters and numbers are available on the 80-character dial.
- I planned the full inscription length before starting.
- I can hold the ring securely in the self-centering chuck.
Common Ring-Engraving Planning Mistakes
- Choosing 2 mm characters without checking usable band height.
- Measuring the outer ring width instead of the inner engravable area.
- Starting before planning the inscription length and spacing.
- Assuming every ring profile provides the same flat engraving surface.
- Using an unstable chuck position that lets the ring shift during marking.
