About this template

A presentation-scale isometric with a generous 20 mm cell pitch. Wide enough to fit a complete axonometric of a small building onto a single A2 sheet, with each cell representing one metre at 1:50 - a popular convention for axonometric site plans in British architectural practice. 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

  • Axonometric site plans at 1:50
  • Whole-building cutaway studies
  • Urban-design block axonometric drawings
  • Concept axonometric for planning submissions

Why Tabloid in landscape

11×17" / "Ledger" - the ANSI B counterpart to A3 for studios on US paper stock. Almost every office multi-function printer accepts it. The landscape orientation gives you 432 mm of horizontal run and 279 mm of vertical, which suits wide subjects - site plans, sequence diagrams, multi-column layouts - where the eye reads left-to-right. 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

Compatible with ISO 5456-3 isometric projection; pitch tuned to ISO 5455 1:50 architectural scale. 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

Large-pitch isometric grids were popularised by James Stirling and the Cambridge architects of the 1970s for axonometric drawings of buildings and urban blocks - the Stirling-Wilford office templates were 20 mm grids on A1.

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 Isometric 30° · 20 mm 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.
