Frequently asked questions
How do I keep the printed grid at the right size?
Print at 100% or Actual size and disable Fit to page. The SVG uses millimetre dimensions; printer margins and hardware can still affect the physical result.
Can I choose dot or isometric paper?
Yes. Choose dots or isometric in Pattern; spacing controls the distance between marks.
Limits and accuracy
Use realistic values. The tool explains assumptions and does not replace professional, official or safety advice where that applies.
