International paper and envelope size reference

Tool powered by Paper Sizes on papersizes.io.

Paper size chart on papersizes.io: envelope sizes, photo sizes, legal and tabloid dimensions, A5 paper, ISO A/B series, and mm or inch conversions.

What is papersizes.io?

Paper Sizes (https://papersizes.io/) is a reference for international paper dimensions—ISO A and B series, US Letter and Legal, envelopes, photography formats, and unit conversions in mm, cm, inches, and points. Teams searching for envelope sizes, photo sizes, legal size paper dimensions, or tabloid paper size comparisons use category pages such as /international-envelope/, /photography/, and /us/legal/. On Uwarp this page embeds the official site for quick lookup during print and layout work. Uwarp does not host the size database.

What papersizes.io offers

Structured reference for print and layout standards.

  1. ISO A and B series: A4, A5, A3, and B formats with width and height in multiple units.

How to use this embed on Uwarp

From lookup to print-ready specs.

  1. Pick the right family: Start with envelopes, ISO A, US, or photography depending on your deliverable.
  2. Open the matching papersizes.io page: Use in-embed navigation to envelope sizes, legal dimensions, or A5 paper entries.
  3. Copy dimensions in your unit: Paste mm or inch values into InDesign, Figma, or production briefs.
  4. Add bleed and margins separately: Paper dimensions are trim size—extend artboard for bleed per your print vendor.
  5. Open papersizes.io in a new tab if needed: Compare pages and deep links may work better outside a restricted iframe.

Tips for accurate print setup

Standards differ by region.

  1. Confirm region before layout: A4 and US Letter are not interchangeable—pick the standard your audience expects.
  2. Match units to the tool: Use mm for print specs; px only when converting at a stated DPI.
  3. Check portrait versus landscape: Swap width and height when orientation changes even if the format name stays the same.
  4. Document envelope and insert pairs: Folded inserts must fit envelope sizes—verify both in the chart.

Who this is for

Print, product, and documentation workflows.

  1. Print and packaging designers: Set trim sizes, envelopes, and dielines from a trusted chart.
  2. Document template authors: Configure Legal, Letter, or A4 templates with correct paper dimensions.
  3. Photography and lab workflows: Reference photo sizes before ordering prints or building galleries.
  4. Global product teams: Compare international paper sizes when shipping multi-region collateral.
