ISBN-13 Barcode Generator – Create high-quality barcodes with the same precision as our software. Download as vector (PDF, EPS, SVG) or raster image (PNG, BMP, JPG) – in CMYK or RGB colors.
ISBN-13 Standard Sizes
The official GS1 specification defines the ten standard sizes SC0–SC9 for ISBN-13. The dimensions of the most commonly used size SC2 are already set as default in the generator. If needed, choose another standard size from the table below, or enter custom width and height.
| Height (mm) | Width (mm) | Width + Add-On 2 | Width + Add-On 5 | |
|---|---|---|---|---|
| SC0 | 21.48 | 30.50 | 37.25 | 44.54 |
| SC1 | 23.34 | 33.56 | 40.99 | 49.01 |
| SC2 | 25.93 | 37.29 | 45.54 | 54.45 |
| SC3 | 28.52 | 41.02 | 50.09 | 59.90 |
| SC4 | 31.12 | 44.75 | 54.65 | 65.34 |
| SC5 | 35.01 | 50.34 | 61.48 | 73.51 |
| SC6 | 38.90 | 55.94 | 68.31 | 81.68 |
| SC7 | 42.78 | 61.53 | 75.14 | 89.84 |
| SC8 | 47.97 | 68.99 | 84.25 | 100.73 |
| SC9 | 51.86 | 74.58 | 91.08 | 108.90 |
Note: ISBN-13 barcodes include the human-readable number with hyphens at the top. This increases the overall height of the resulting graphic. However, this is common and correct – the dimensions of the barcode symbol itself still comply with the specification.
The following image shows the standard size SC2 with all relevant dimensions, including the left and right margins (“quiet zones”). Our barcode generator automatically sets all measurements precisely in accordance with the GS1 specification.
OCR-B – The Standard Font for ISBN-13 Barcodes
For the human-readable ISBN-13 number below the barcode, our generator uses the font OCR-B by default. This is recommended by GS1 for all barcodes in the UPC/EAN family, including ISBN-13. Additional fonts are available for selection. The Text Offset from Symbol setting allows adjusting the spacing between the human-readable number and the barcode symbol. Negative values can also be used to compensate for excessive white space.
PDF and EPS – Common Vector Formats for ISBN-13
For placing an ISBN-13 barcode on the back cover of a book, the vector formats PDF and EPS are the preferred choice. Both formats are functionally equivalent: they support CMYK colors and transparent backgrounds for barcodes on colored covers. EPS files additionally contain an embedded TIFF preview, which can be used by DTP applications without native EPS display, for example in older versions of QuarkXPress.
All three vector formats (PDF, EPS, SVG) store coordinates with a precision of six decimal places. The two textual portions of the ISBN-13 barcode are converted to outlines, so no fonts are required when handing over to print shops.
Raster formats (PNG, BMP, JPG) store the DPI value in the file header, so that resolution and physical dimensions in millimeters are directly contained in the file and can be correctly interpreted by layout applications. The barcode bars are precisely aligned to the selected print resolution, preventing aliasing and other unwanted effects. This keeps barcodes fully scannable even at low print resolutions (e.g., 203 or 300 DPI). PNG supports transparent backgrounds.
