Isometric 30° · 5 mm on A4 · Portrait
The textbook isometric grid - three axes at 120°, 5 mm cell pitch.
A drafting paper library · 48 grid types
Printable technical drawing paper, calibrated to the standard.
GridCraft is a free catalogue of specialty printable grids for architects, civil engineers, illustrators and makers - isometric, axonometric, perspective, cross-section, pre-scaled architectural sheets, knitting charts, polar plots and more. Every grid follows real ISO and ANSI conventions, so what prints on your A4 tray actually measures.

Choose by grid family
Pick the projection that fits the drawing
Fourteen grid families covering every common technical-drawing task. Each family is described in plain language alongside its standards lineage so you can match the page to the discipline rather than to a visual whim.
Isometric
The textbook isometric grid - three axes at 120°, 5 mm cell pitch.
Axonometric
Dimetric grid with two equal axes at 30° and a third at 60°.
Perspective
Single vanishing point on a centred horizon - the corridor view.
Cross-Section
Fine 1 mm engineering grid with bold 5 mm and 10 mm reference lines.
Scale Grid
1:20 detail grid - every 25 mm cell equals 500 mm on site.
Floor Plan
Imperial 1/4" square grid - the legacy North American floor-plan workhorse.
Dot Grid
Subtle 5 mm dot lattice - bullet-journal and analytic-sketch staple.
Logarithmic
One-decade log on Y, linear on X - for exponentials and decay curves.
Polar
Concentric circles with 5° radial spokes - for polar plots and antenna patterns.
Hexagonal
Flat-top regular hexagons at 5 mm pitch.
Knitting & Textile
Square chart grid for stranded colourwork and intarsia.
Storyboard
Sequential 16:9 broadcast-ratio frames with annotation gutters.
Calligraphy
Slanted baseline-and-cap-height ruling for italic hand.
Music & Notation
Five-line music staff with consistent inter-staff spacing.
Choose by profession
Curated grid sets for the way you actually work
Each profession has its own grid traditions - an architect reaches for different sheets than an illustrator or a knitter. The collections below pull together the grids most-used by each discipline, with the standards and history behind every choice.
For Architects
Plan, section and axonometric grids calibrated to ISO 5455 and ANSI Y14.1.
For Interior Designers
Furniture-scale plans, 1/2" kitchen-and-bath grids, and oblique cabinet sketches.
For Illustrators
Perspective, isometric and storyboard grids for visual storytelling.
For Engineers
Cross-section, semi-log and engineering quad for calculation and measurement.
For Civil Engineers
Site-scale, urban-scale and survey grids for civil and infrastructure work.
For Game Designers
Hex maps, dimetric grids and isometric sheets for board and video games.
For Teachers
Maths, science and design-tech grids for classroom photocopying.
For Makers & Hobbyists
Knitting charts, hex grids, calligraphy guides and bullet-journal dot grids.
Choose by paper size
Print-tray friendly across both standards systems
Every grid is rendered against ISO A-series sheets and the ANSI/US loose family, so the same template works on a Berlin studio's plotter and a Brooklyn studio's desk inkjet.
Why GridCraft is different
Calibrated, not decorative.
Standards-true
Every grid is generated from real measurements - ISO 5455 preferred scales, ISO 5457 sheet sizes, ANSI Y14.1 conventions, ISO 128-20 line weights. A 1:50 page is genuinely 1:50 when you print it at 100%.
Architect-first vocabulary
The catalogue is organised the way a designer thinks - by projection, by scale, by sheet, by profession - not by alphabetical order in a clip-art library.
Free, forever, no log-in
No watermarks, no email gates, no monthly limits. Pages render straight from the server, every link works, the whole catalogue is browseable without an account.
Vector by default
Every download is an SVG with physical millimetre dimensions baked into the file, so it prints at exact 1:1 scale on any compliant printer driver. Scale up or down without losing line crispness.
Featured this week
Templates the studio reaches for
Hand-picked sheets that solve the kind of problem that lands on a designer's desk on a Monday morning - a tower study at 1:200, an isometric exploded view, a cross-section of a stair detail.

Guides
Read before you print
Three short guides every designer reaching for printable graph paper should read first.
How to print graph paper at exact 1:1 scale
Why "fit to page" silently breaks every measurement, the right printer driver settings, and how to test your printer's calibration in 30 seconds.
Architectural scale guide: 1:20 to 1:1000
What every common architectural and engineering scale is for, when to use which, and how the ISO 5455 preferred-scales list shapes European practice.
Projection guide: parallel vs vanishing-point
The difference between isometric, axonometric, oblique and perspective - and which one to pick for any given drawing brief.
Iso vs axo vs perspective: a side-by-side
A practical comparison with measurability, drawing speed, and best-fit subject for each of the three pictorial families.
