Made to measure.
Original geometry, explicit dimensions, and a practical way to check the physical print.
The template library is generated by our own drawing code. Every ready-made page is a specific recipe: a paper format, an orientation, and a measurement or layout that changes the output. The studio uses the same drawing model for customized sheets. Colors and personal titles are settings, rather than separate library pages.
One measurement model.
All geometry starts in millimeters. One inch is exactly 25.4 mm, and one PDF point is 1/72 inch. We convert millimeters to PDF points with points = millimeters × 72 ÷ 25.4. PDF page dimensions and vector paths use this same conversion. SVG files declare their size in millimeters.
The conversion follows W3C absolute-length definitions. A physical screen preview is not a ruler: the page is scaled to fit, and displays can map CSS units differently from printed measurements.
The size of the sheet.
Supported formats are A3, A4, A5, A6, ISO B5, US Letter, US Legal, and Half Letter. The W3C CSS Paged Media draft documents named paper dimensions and the distinction between ISO B5 and JIS B5. Our paper-size table lists every value used by the renderer.
How to read the pattern measurements.
| Pattern | What its value means |
|---|---|
| Square or dot grid | Adjacent line or dot-center spacing |
| Isometric / triangle lattice | Triangle edge; row height = edge × √3 ÷ 2 |
| Hexagon | Edge length; width = 2 × edge; height = √3 × edge |
| Circle | Diameter; radius = diameter ÷ 2 |
| Cross stitch | Count in stitches/inch; actual pitch = 25.4 ÷ count mm |
| Knitting | Stitches and rows per 100 mm (10 cm) |
| Calligraphy | X-height with 1:1:1 bands and 55° slant guides |
| Storyboard | Panel count; each frame has a 16:9 ratio |
Stitch charts need clear scale labels.
DMC’s Aida description defines fabric count as stitches per inch. Our default cross-stitch chart is at 1:1 drafting scale. Studio enlargement multiplies each cell’s physical size and is shown in the sheet specifications.
For knitting, a measured 10 cm swatch with S stitches and R rows gives a cell width of 100/S mm and a height of 100/R mm. Craft Yarn Council’s gauge guidance explains why measuring the actual swatch matters. Our presets are drafting examples, not claims about yarn weights or recommended tension. Four inches is 101.6 mm; the studio’s gauge controls explicitly use 100 mm.
Fit, margins, and shapes.
Ready-made sheets have 10 mm outer margins. Full-cell grids are centered within the available area. Circle and hexagon cutting sheets include only complete shapes. Combinations that cannot fit a complete shape or a readable staff layout are omitted from the library. Custom settings show a warning when they do not fit.
For a quilt hexagon, the solid outline is the finished paper piece. The optional fabric allowance is measured perpendicular to each edge. The outer regular hexagon therefore uses edge + allowance ÷ cos(30°), shown as a dashed line.
What is checked.
The build checks recipe identities, page fit, physical-unit conversion, representative pattern geometry, PDF structure, links, downloads, and metadata. Browser checks cover customization and pack export. These checks validate the generated files; they cannot test your printer’s paper feed or scaling.
Use the print-scale check before a project where physical dimensions matter. Adobe’s print settings distinguish Actual Size from Fit and other scaling options.
How this project was created.
AI assistance was used in developing the site and drafting its explanations. The measured templates are generated by deterministic geometry, rather than image generation or copied scans. We do not present automated text as a named expert’s advice or claim that a preset is a professionally reviewed craft pattern.
