Resize Image to 1200×1800 (4×6 Print @ 300 DPI)

1200×1800 pixels is a standard 4×6 inch photo print at 300 DPI — the size photo labs, drugstore kiosks and home photo printers expect for the most common print format there is. A 4×6 has a 2:3 aspect ratio, which matches most DSLR and phone-camera photos, so cropping to 1200×1800 usually keeps almost the whole frame while guaranteeing enough pixels for a sharp print. This tool crops your photo to that exact 2:3 print size on your device, so a family photo never gets uploaded to an online lab just to be resized.

Good to know

Outputs exactly 1200 × 1800 pixels — a 4 × 6 inch print (2:3 ratio) at 300 DPI.

2:3 matches most camera and phone photos, so the crop usually keeps nearly the whole picture.

300 DPI is photo-lab print quality, so the print comes out sharp rather than pixelated.

"Cover" fit fills the full 4×6 frame and trims overflow, so there's no white border baked into the image.

For a landscape 4×6, use the 1800×1200 preset (swap width and height) so the photo isn't rotated to fit.

Frequently Asked Questions

Why is a 4×6 print 1200×1800 pixels? ▼

A 4×6 inch print at 300 DPI needs 4 × 300 = 1200 pixels on the short side and 6 × 300 = 1800 pixels on the long side. That's the pixel count a photo lab wants for a crisp 4×6 print, which is why 1200×1800 is the standard size to resize to.

Will my whole photo fit a 4×6, or will it be cropped? ▼

A 4×6 is a 2:3 ratio, which is the same shape as most DSLR and phone photos, so usually very little is lost. If your photo is a different shape — say a square or a 4:5 portrait — the cover crop will trim it to 2:3, so check your subject sits within the frame before exporting.

Can I use 1200×1800 for both portrait and landscape prints? ▼

1200×1800 is portrait (taller than wide). For a landscape 4×6, resize to 1800×1200 instead so the photo keeps its orientation rather than being forced to rotate. The pixel budget is identical — only the width and height swap.

Is my photo uploaded to resize it? ▼

No. The resize runs on a canvas in your browser, so your photo never leaves your device before you send it to print.
