How this service works
Standard US trade book trim sizes in inches and mm, or look up one size like 6x9 and its closest standard.
Output
Returns either the full list of standard US trade book trim sizes (with width and height in both inches and mm, and the use/category label for each), or — when a specific size like '6x9' is queried — returns that size's details plus its nearest standard match, aspect ratio, and match reasoning.
Example use cases
Validating a custom book trim size
“I'm planning to print a book at 5.25x8 inches — is that a recognized US trade trim size, and if not, what's the closest standard I should use instead?”
Choosing a trim size for a new novel
“Can you show me all the standard US trade book trim sizes so I can pick the right one for my novel? I want to see both inches and millimeters.”
Confirming trim size for a print-on-demand order
“My print-on-demand service needs a standard trim size — I was thinking 6x9. Can you confirm that's a real standard and tell me its exact dimensions in mm too?”

Endpoint
GEThttps://publishing-calc.x402tookit.com/trim-sizes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative US trade book trim size data, want to validate whether a specific width×height is a recognized standard, or need to find the closest standard to a custom size — especially when building publishing workflows, print-on-demand tools, or book formatting assistants.
Side effects
- Malformed size string (e.g. missing 'x', non-numeric values) may return an error or null match
- A size wildly outside standard ranges may return no nearest match or a low-confidence match
- Network or payment (x402) failures result in no response
