A precision-engineered 10mm grid paper template, built on exact vector measurements. On US Letter (8.5 × 11 in), a 10mm grid fills the 175.9 × 239.4mm usable area with 18 vertical and 24 horizontal lines, forming roughly 391 individual grid squares – sized for basic math and large-scale layout.

Key Features:

Exact Measurements: Precisely calibrated 10mm dimensions and line spacing.
Color Profile: Neutral, low-contrast gray reduces eye strain and keeps handwriting distinct.
Perfect Fit: Formatted natively for standard US Letter (8.5 x 11 inches).

By the Numbers

Grid spacing: 10mm (0.39in) in both directions
Grid lines: 18 vertical × 24 horizontal
Approximate squares: 391
Usable grid area: 175.9 × 239.4mm, inside a uniform 20mm margin
Stepping down to 5mm spacing: raises the count to roughly 1,645 squares – finer detail at the cost of a busier-looking page

Also Available

This grid also comes at 1mm, 2mm, 5mm spacing, in gray, blue, black, and every paper size from A5 to Legal. Browse the full set from the graph paper category page if this exact combination isn’t quite right.

Best Uses and Applications

Foundational Math: Standard density for middle school and high school mathematics coursework.
Basic Charting: A grid large enough to label each square with a legible number.
Floor Plans: A practical scale for rough interior design layouts sketched by hand.

Printing Recommendations

For accurate measurements, always set your print dialog to “Actual Size” or 100% scale – never “Fit to Page,” which silently rescales every line, dot, or grid square on the sheet. Most consumer print drivers default to “Fit to Page” or “Shrink to Fit,” so it’s worth checking the scale setting even if you’ve printed from this browser before. For technical work, print on 24lb+ paper so fine pen lines don’t feather into the grid.

Print a single test page first and check the spacing with a ruler before printing a full batch.
If lines look too faint or too heavy on your printer, use the Interactive Generator to adjust opacity before your next print run.
Store extra printed sheets flat rather than folded – a crease across ruled lines or a grid is far more noticeable than one across blank paper.

Frequently Asked Questions

Can I print this LETTER template on a different paper size?

Yes, but the measurements are calibrated specifically for US Letter (8.5 × 11 in). If you print on a different sheet size without matching scale, the printer will stretch or shrink every line to fit, which throws off the exact spacing. Use the generator to rebuild the template natively for your target size instead of rescaling this one.

Does the line weight interfere with scanning?

We intentionally calibrated the line opacity to 80% with a 0.5pt weight. This is dark enough to guide your pen but light enough to fall back when scanned or photographed, keeping your work highly legible even at the finer spacings, where more lines are packed into the same page.

What does the Interactive Generator let me change that this static PDF doesn’t?

This page is a fixed, pre-configured version. The generator behind it exposes the same underlying settings – paper size, orientation, spacing, color, line weight, and margins – as live sliders and color pickers, with a preview that updates as you drag them. It’s the same PDF engine, just with the defaults unlocked so you can land on a variant that isn’t listed as its own page.
