Convert physical business card dimensions to pixel values. Supports custom DPI settings for both print design and screen display scenarios.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Choose a business-card size preset and a DPI value to see its width and height in whole pixels. The calculator uses the selected physical dimensions in millimeters, converts each to inches, multiplies by DPI, and rounds each result to the nearest pixel.
NIST defines one inch as exactly 25.4 millimeters. DPI here means dots per inch: a higher value produces more pixels for the same physical dimensions. For example, the US/CA preset is listed as 89 × 51 mm; at 300 DPI its rounded result is 1,051 × 602 px.
The preset list also includes ISO, Japan, China, Australia, and other card-size choices. Select the one matching the physical card you intend to make; region labels help identify a starting dimension but do not establish your print shop’s required artwork size.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Choose the business-card dimensions that match your region or supplier’s trim size. The selected width and height are displayed in millimeters.
Choose a value from 72 to 600 DPI using the slider or enter a value. Higher DPI increases pixel dimensions while the physical card size stays the same.
Use the displayed whole-pixel values as the trim-size raster dimensions calculated from that preset. Copy each dimension if needed.
At 300 DPI, the built-in US/CA 89 × 51 mm preset calculates to approximately 1,051 × 602 pixels because the calculator uses the millimeter values shown in the preset and rounds the results.
Use cases
See how the tool fits into real work and everyday tasks.
A designer can select the intended card trim dimensions and DPI to estimate a pixel canvas before adding text and artwork.
Teams ordering cards in more than one market can compare the listed presets and confirm the physical size with each supplier.
Learners can hold the physical size constant and change DPI to see why print dimensions in pixels vary with the selected resolution.
Q&A
Find concise answers to common questions and confusing cases.
No. The physical size comes from the chosen preset. DPI sets the number of pixels used to represent each inch of that size, so a larger DPI means more pixels for the same card.
No. It calculates the selected card dimensions only. Add bleed and keep text inside a safe area according to the printer’s current template and production instructions.
Some presets are stored as whole millimeter values. Converting and rounding those values can produce a pixel count a little different from calculating from a separate inch measurement. Check the physical dimensions and supplier template when the exact trim size matters.
Notes
Review scope, result limitations, and important precautions before use.
This calculator does not add bleed, crop marks, safe margins, color settings, or printer-specific export requirements. Pixel dimensions alone do not guarantee suitable print resolution or finished output. Check the card stock, trim dimensions, bleed, and file specifications supplied by the printer before sending artwork.
Regional size labels are presets, not a universal business-card standard. If an exact physical size is required, use the supplier’s stated measurements and verify that the selected preset matches them.
