よくある質問

Does more megapixels always mean better image quality?

Not necessarily — megapixels only measure resolution (pixel count); sensor size, lens quality, and pixel size also strongly affect image quality, especially in low light.

How many megapixels do I need for a large print?

It depends on the print size and viewing distance — the print-size calculator shows the maximum print dimensions your resolution supports at a chosen DPI.

What inputs does the Megapixel Calculator need?

You'll need to provide: Image Width, Image Height. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Megapixel Calculator?

The Megapixel Calculator applies the formula exactly as calculated — Megapixels = (width in pixels × height in pixels) / 1,000,000. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Megapixel Calculator free to use?

Yes, the Megapixel Calculator is completely free, requires no signup, and runs instantly in your browser.
