How does your print look?
Measure the bars with a ruler, then pick the option that matches. This tells you if your print was scaled.


- 1.Horizontal 100 mm bar with 10 mm ticks
- 2.Second 100 mm bar (A4) or 4 in bar (Letter)
- 3.Vertical 100 mm bar
- 4.20, 30 and 40 mm squares
- 5.Bank-card size box, 85.6 x 54 mm
- 6.Nested frames at 3, 6, 9 and 12 mm
- Measure from the 0 tick to the 100 tick with a metal or plastic ruler, not from the paper edge.
- Check both the horizontal and vertical bars. If only one is wrong, the scaling is uneven.
- Use the 4 in bar on Letter paper, or the second 100 mm bar on A4, to confirm the first reading.
