Printable paper
Choose a ready-made page when the standard pattern is enough. Use the file that matches the sheet in your printer.
- 5 mm graph paper: A4 and Letter PDFs
- Dot grid paper for notes and layouts
- Lined paper and writing space
- Printable ruler with a scale check
Paper sizes
Check nominal dimensions, proportions and conversions before setting up a document or substituting a different sheet.
- A4 vs Letter: what changes when printing?
- A5 and the folded-A4 difference
- ISO B5 vs JIS B5
- Photo sizes, ratios and frame fit
Printing help
Work through the settings behind common problems: unwanted shrinking, page order, cropping and label alignment.
- Print a PDF at Actual Size or 100%
- Resize a PDF: print scale vs saved page size
- Arrange pages for a folded booklet
- Diagnose label misalignment
Calculators and tools
Use a worked calculation instead of guessing a dimension, resolution or paper-weight conversion.
- Convert millimeters, inches and PDF points
- Calculate print size and image PPI
- Convert GSM and pounds using the paper grade
Printing a measured pattern? Start with one test sheet.
- Match the PDF page size to the paper loaded in the printer.
- Choose Actual Size or 100% when the physical measurements must stay unchanged.
- Measure a known reference in both directions. Check clipping and readability before printing more copies.
A digitally correct file cannot establish what your particular printer will produce. A fit calculation is a model; a measured test print checks the output.
Original resources, with clear limits.
Our printable patterns, diagrams and calculators are created for PaperGridly. Guides distinguish nominal paper dimensions, calculated examples and printer-dependent behavior. Relevant references are linked in the articles, including ISO 216 for A- and B-series trimmed sizes and Adobe’s print page-sizing documentation.
