Printable Diagonal Grid Paper
Diagonal grid paper rules two families of lines at 45°, crossing to form a diamond lattice. Add the optional square grid and you get the on-point layout used for quilt design, diagonal tile patterns and lettering slant practice.

On-point layouts
Quilters call a block rotated 45° 'on point'. Designing on-point layouts on ordinary square graph paper means constantly drawing diagonals by hand; diagonal grid paper prints them for you, so blocks, setting triangles and sashing all land on ruled lines. The optional square grid gives you both orientations at once, which is what you need when a design mixes straight-set and on-point blocks.
Lettering and slant guides
Forty-five degrees is a common slant for certain italic and brush-lettering styles, and a diagonal grid gives you a consistent angle reference across the whole page. If you need a different slant angle for calligraphy specifically, the calligraphy practice paper on this site lets you set the angle precisely.
Pattern and tile design
Diagonal lattices underpin harlequin and argyle patterns, diagonal tile layouts, herringbone approximations and many decorative borders. Because the two line families cross at right angles to each other, every diamond is a square rotated 45° — so anything you design translates directly back to a square-grid construction.
Frequently Asked Questions
What is diagonal grid paper used for?
Quilt design (especially on-point block layouts), diagonal and harlequin tile patterns, lettering slant guides, and any pattern work built on a diamond lattice.
Can I get both diagonal and square lines?
Yes — turn on the square grid option and both sets print together, with the square grid spaced so its intersections align with the diagonal crossings.
What does 'on point' mean in quilting?
A block set on point is rotated 45° so it reads as a diamond rather than a square. Diagonal grid paper is the easiest way to plan those layouts, since the block edges follow printed lines.
What spacing should I choose?
For quilt planning, pick a spacing where one square represents a convenient unit — 1/4 inch per inch of finished block is common. For pattern and lettering work, choose whatever gives a comfortable density on the page.
Printing Tips
- Print at 100% scale.Turn off “fit to page” and “shrink oversized pages” — otherwise your printer rescales the sheet and the measurements no longer match.
- Match the paper size. Choose the same size here as the paper in your tray. Printing a Letter PDF on A4 (or the reverse) scales it.
- Lighter lines print better. A light grey or blue guides your work without competing with it — and it uses far less ink.
- Use heavier paper for wet media. 100gsm and up for fountain pens and markers; standard copier paper is fine for pencil.
