Photography Print Size Calculator
x402
Photography Print Size Calculator is a paid API for AI agents from photo-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-04).
Calculates print dimensions (inches and cm) from image pixel dimensions at various DPI settings, or computes required pixels/megapixels for a target print size, with viewing distance advice.

How this service works
Print size from image pixels at a DPI, or the pixels and megapixels needed for a print size; with viewing-distance advice.
Output
Returns print dimensions in inches and centimeters at each common DPI (100, 150, 200, 300) and at the chosen DPI, plus the DPI used, the timestamp, and optionally the pixels or megapixels required for a specified target print size, along with viewing distance advice.
Example use cases
Check if a photo is print-ready
“I have an image that's 3000 x 2000 pixels and I want to print it at 300 DPI — what print size will that give me in inches and centimeters?”
Find pixels needed for large format
“I want to order a 24 x 36 inch poster print at 300 DPI — how many pixels wide and tall does my image need to be, and how many megapixels is that?”
Compare print quality at multiple DPIs
“My photo is 4000 x 3000 pixels — show me the print dimensions I'd get at 100, 150, 200, and 300 DPI so I can decide what size to order.”
Technical details
Endpoint
GEThttps://photo-calc.x402tookit.com/print-size?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to convert between image pixel dimensions and physical print sizes, or determine the minimum resolution required for a given print format. Ideal for photography workflows, print ordering, or advising users on whether their image file is large enough for a desired print size. Prefer this over generic unit converters because it handles multi-DPI comparison, megapixel calculation, and viewing distance advice in a single photography-specific response.
Side effects
- Missing both pixel dimensions and print dimensions — endpoint needs either widthPx/heightPx or printWidthIn/printHeightIn to compute anything
- Non-positive or zero pixel/inch values causing invalid calculation results
- Extremely low DPI values producing unrealistically large print sizes with quality warnings
- Network timeout or payment failure returning no result
