About

Incorrect resolution settings are the silent killer of digital art and print production. A canvas set too small results in pixelation that cannot be fixed, while an excessively large canvas causes software lag, crashes, and unmanageable file sizes. This engineering-grade tool eliminates the guesswork by bridging the gap between digital raster data and physical output.

We have engineered this calculator for Pre-press specialists, UI/UX designers, and Digital Artists who demand precision. Unlike basic converters, this tool calculates uncompressed memory allocation (RAM) to prevent hardware bottlenecks and cross-references your dimensions against industry standards for print and screen.

Formulas

Precise conversion relies on the correlation between linear units and pixel density.

{

Pixel = Inch × DPIInch = mm25.4RAM_MB ≈ W × H × Channels × BitDepth8,388,608

Note: The RAM formula divides by 8,388,608 (which is 1024² × 8 bits) to convert raw bits to Megabytes. Standard editing uses 4 channels (RGBA) at 8 bits/channel.

Frequently Asked Questions

While often used interchangeably, PPI (Pixels Per Inch) refers to the density of pixels on a digital screen or in a file, whereas DPI (Dots Per Inch) refers to the density of ink dots a printer sprays on paper. For canvas setup, you effectively set the PPI value to match the target printer's required fidelity.

Standard 8-bit color uses 256 shades per channel (Red, Green, Blue). 16-bit color uses 65,536 shades per channel, providing smoother gradients but doubling the data required for every single pixel. This literally multiplies your RAM usage by 2.

Divide your image's pixel width by 300 to get the maximum inches for high-quality handheld print (like a brochure). Divide by 150 for posters viewed from a few feet away. For example, a 3000px wide image prints sharply at 10 inches (3000 / 300 = 10).

Platforms like Instagram compress images heavily. The standard is 72 PPI (screen density), but it is recommended to design at exactly 1080px or 2160px width to ensure the compression algorithm doesn't blur your lines. Physical inches do not matter for social media, only pixel dimensions.

No. Changing DPI from 72 to 300 without changing pixel dimensions just makes the physical print size smaller. If you enable "Resample" to keep the physical size while increasing DPI, the software invents new pixels (interpolation), which usually results in a blurry image.
