About this template

The most-used scale in European architectural practice, here printed as a ready-to-use grid. Every 10 mm square represents one square metre on site, so a 5 m × 4 m room snaps neatly into a 50 mm × 40 mm patch on the page. Bold every-fifth-line hatching gives you a 5 m reference rhythm. See also: A short reading list on technical drawing standards can help you put any of these grids in their historical and standards-based context.

Best used for

  • Whole-building floor plans
  • Planning-application drawings
  • Site layout at building scale
  • Tender drawings for general contractors

Why Tabloid in portrait

11×17" / "Ledger" - the ANSI B counterpart to A3 for studios on US paper stock. Almost every office multi-function printer accepts it. The portrait orientation gives you 279 mm of horizontal run and 432 mm of vertical, which suits tall subjects - elevations, sections, single-column drawings - where the eye reads top-to-bottom. Trim and bleed allowances on consumer printers will normally remove a 5 mm strip from each edge; this grid is generated to remain measurable even after that trim, with no critical content placed inside the printer-margin band.

Standards and lineage

Recommended preferred scale per ISO 5455:1979 for building plans. The Tabloid sheet itself follows ANSI B, and the title-block conventions assumed by this template come from ISO 5457:1999 - the international standard governing how technical drawings are framed, dated, and signed. Background reading: See our scale-and-projection guides for a deeper dive on how all the standards in this lineage interact in practice.

A short history of this grid

1:100 plans came to dominate European practice once the A0–A4 ISO sheet sizes were widely adopted, since most domestic-scale buildings fit cleanly onto an A2 or A3 sheet at this ratio.

Printing notes

For accurate output, print at 100 % scale - never "fit to page", which silently shrinks the sheet by 4–6 % and breaks every measured cell. Use a laser printer if the grid will be traced over with ink, since inkjet inks bleed through technical pen and pencil. If your printer cannot handle the full Tabloid sheet, scale the SVG to the next-smaller paper size before printing - every GridCraft grid is delivered as vector artwork so it scales cleanly. The downloaded SVG carries the physical sheet dimensions in millimetres, so a compliant print driver should print at 1:1 by default. Our how-to-print guide walks through the calibration test in 30 seconds.

Designer's note

Specialty grids reward the discipline of choosing the right sheet for the right drawing. A Architect Scale · 1:100 on Tabloid is not a one-size-fits-all sheet - it's a calibrated tool for a specific class of problem. Use it where the page suits the drawing; reach for a different sheet when it doesn't. The catalogue is large precisely so you don't have to compromise on the projection, scale or sheet size.
