Print it once, keep it by your cutting mat, and never do the maths in your head again. One sheet gives you a true-scale ruler in millimetres and inches (with a calibration mark so you can confirm your printer did not shrink the page), the conversion rule (1:12 = real size divided by 12) plus a quick chart, standard 1:12 heights (chair seat, dining table, kitchen worktop, shelf spacing, door, ceiling), and typical room sizes at 1:12.
USE THE COUPON CODE FREEGUIDE AT CHECKOUT.
WHAT YOU GET
- Two print-ready PDF files: US Letter and A4
- Printable calibration ruler in millimetres and inches
- Real size to 1:12 conversion chart
- Standard furniture heights at 1:12 scale
- Typical room dimensions at 1:12 scale

HOW TO PRINT
Print at 100% / Actual Size — turn OFF 'fit to page'. Then check the ruler spans exactly 170 mm (6.69 in). Ordinary paper is fine.
