Each paper size includes a proportion bar showing its area relative to A0 - the largest ISO size. This makes it immediately obvious how sizes compare to each other without needing to visualise raw numbers in your head.
Common Use Cases for PDF Paper Size Reference
Graphic Design & Print Production
Look up exact A3, A4, or Tabloid dimensions in mm before setting up a new document in Illustrator, InDesign, or Figma. The pdf paper size reference saves you from leaving your design app to search for standard dimensions.
PDF Document Creation
When creating PDFs with pdf-lib, PDFKit, or ReportLab, you need page dimensions in PDF points. Use the pdf paper size reference to look up A4 (595 × 842 pt) or US Letter (612 × 792 pt) without manually converting from mm.
Print Shop & Prepress
Confirm bleed, trim, and media box dimensions for any standard paper size before sending files to a commercial printer. The pdf paper size reference covers ISO, ANSI, and Arch series used in both offset and digital printing.
Developer Reference
When building PDF generation libraries or setting page dimensions programmatically, the pdf paper size reference provides exact dimensions in PDF points alongside mm and inches - eliminating the need to hardcode magic numbers.
Office & Document Management
Quickly check whether a document's page size matches the required standard for a submission portal or printer tray. Use the pdf paper size reference to compare ISO and ANSI sizes when working across international offices.
Publishing & Book Layout
Book designers working with B5, JIS B5, or custom trim sizes need precise dimensions for typesetting and spine calculation. The pdf paper size reference covers both ISO B and JIS B series with exact mm measurements.
Understanding PDF Paper Size Standards
What Are ISO 216 and ANSI Paper Size Standards?
Paper sizes are defined by two major standards: ISO 216 (used in most of the world) and ANSI/ASME Y14.1 (used primarily in North America). ISO 216 defines the A-series, B-series, and C-series - all sharing an aspect ratio of √2 (approximately 1:1.414). This ratio means that folding an A3 sheet in half produces two A4 pages, folding A4 produces A5, and so on. The ANSI standard defines Letter, Legal, Tabloid, and ANSI A through E - the sizes commonly found in US printers and PDF templates. The pdf paper size reference covers both standards along with JIS B-series (used in Japan) and the Arch series (used in architectural and engineering drawings).
How PDF Points Relate to Millimetres and Inches
PDF documents store all page dimensions internally in PDF points, where 1 point = 1/72 inch. This means an A4 page (210 × 297 mm) is stored as 595 × 842 points, and a US Letter page (216 × 279 mm) is stored as 612 × 792 points. When building PDFs programmatically - using pdf-lib, PDFKit, iTextSharp, or any PDF library - you must supply dimensions in points. The pdf paper size reference provides all three units (mm, inches, and points) in a single lookup so you never need to convert manually.
- 1 point = 1/72 inch = ~0.353 mm
- 1 inch = 72 points = 25.4 mm
- A4 in points: 595 × 842 pt
- US Letter in points: 612 × 792 pt
ISO Series Sizes at a Glance
- ISO A-series - the most widely used international paper sizes. A4 (210 × 297 mm) is the global standard for office documents, reports, and forms. A3 (297 × 420 mm) is used for posters, drawings, and spreadsheets.
- ISO B-series - intermediate sizes between A-series sheets. B5 (176 × 250 mm) is commonly used for books and notebooks; B4 for some newspapers and print formats.
- ISO C-series - envelope sizes designed to fit A-series sheets. C4 holds an unfolded A4; C5 holds a folded A4; DL (110 × 220 mm) holds A4 folded into thirds.
- ANSI / North American - Letter (216 × 279 mm) and Legal (216 × 356 mm) are the dominant office sizes in the US and Canada. Tabloid (279 × 432 mm) is used for newspapers and posters.
Using This Reference in Your Workflow
The pdf paper size reference is fully client-side - no data leaves your browser. You can filter the table to a specific series, switch between mm, cm, inches, and points with one click, and download the full table as CSV for use in spreadsheets, design briefs, or developer documentation. The proportion bar alongside each size gives an instant visual sense of how large each sheet is relative to A0, which is helpful when comparing sizes across series.

Frequently Asked Questions About PDF Paper Sizes
A4 (210 × 297 mm / 8.27 × 11.69 in) is the international standard defined by ISO 216. US Letter (216 × 279 mm / 8.5 × 11 in) is the North American standard. Letter is slightly wider and shorter than A4. If you set a document to A4 and print on Letter paper (or vice versa), text near the edges may be clipped. Always match your PDF page size to the paper loaded in your printer.
PDF dimensions are stored internally in points where 1 pt = 1/72 inch. To convert: multiply mm by 2.8346 to get points (e.g., A4 width 210 mm × 2.8346 = 595 pt). The pdf paper size reference shows points for every size - select "pt" from the unit toggle and read the values directly without any calculation.
ISO B-series sizes are intermediate between A-series: B0 (1000 × 1414 mm), B1 (707 × 1000 mm), B2 (500 × 707 mm), B3 (353 × 500 mm), B4 (250 × 353 mm), B5 (176 × 250 mm), B6 (125 × 176 mm), B7 (88 × 125 mm), B8 (62 × 88 mm). B5 is popular for books and notebooks; B4 is used in some newspaper and printing formats.
ISO B-series and JIS B-series both sit between A-series sizes, but they use different formulas. ISO B5 is 176 × 250 mm; JIS B5 is 182 × 257 mm. JIS sizes are slightly larger. JIS B-series is the standard for notebooks and stationery in Japan. Use this reference to compare them side by side by filtering to "ISO B" or "JIS B".
ISO C-series defines envelope sizes designed to hold ISO A-series sheets. C4 (229 × 324 mm) holds an unfolded A4 sheet; C5 (162 × 229 mm) holds A4 folded in half; C6 (114 × 162 mm) holds A4 folded in quarters. DL (110 × 220 mm) - short for "Dimension Lengthwise" - holds an A4 sheet folded into thirds and is the most common business envelope format.
ANSI paper sizes are defined by the American National Standards Institute for engineering and technical drawings. ANSI A (216 × 279 mm) is equivalent to US Letter; ANSI B (279 × 432 mm) is Tabloid/Ledger; ANSI C through E scale up progressively for large-format technical drawings. North American office sizes like Letter, Legal, Half Letter, and Executive are also covered in this reference.
Yes. Click the CSV button in the tool to download the complete paper size table as a CSV file. The CSV includes Name, Series, Width and Height in mm, cm, inches, and PDF points, plus the Standard column - ready to open in Excel, Google Sheets, LibreOffice Calc, or any data tool.
All PDF page dimensions are stored in points internally. When creating PDFs programmatically with pdf-lib, PDFKit, iTextSharp, Apache PDFBox, or similar libraries, you set page width and height in points. Most APIs do not automatically convert from mm. The pdf paper size reference gives you the correct point values for every standard size so you can set them directly in code.
