About 1 mm graph paper

Each square measures 1 mm (≈ 1/25 in). A portrait page holds 210 × 297 squares on A4 and 215 × 279 on Letter. 1 mm graph paper is the size of choice for:

  • Technical drawing with millimetre-accurate dimensions
  • Histology and microscopy sketches
  • Scale plans at 1:100, where one square is 10 cm

All PDFs are vector graphics — perfect print quality at any zoom. Available in A4, A3, Letter, Legal, and A5, portrait or landscape, in nine color options.
