Everything You Need to Know About 4×6 Photo Printing
The 4×6 inch photograph is the most popular standard print size worldwide. It is the default size at every major photo printing service — Walgreens, CVS, Costco, Walmart, Amazon Photos, and Shutterfly all print 4×6 photos as their most affordable option. Whether you are printing vacation memories, family portraits, event photography, or professional headshots, getting your image to the correct 1200×1800 pixel dimensions at 300 DPI ensures a crisp, professional-quality print every time.
Why 1200×1800 Pixels?
Print quality is measured in DPI (dots per inch). For professional-quality prints, 300 DPI is the industry standard. At 300 DPI, a 4-inch side requires 4 × 300 = 1200 pixels, and a 6-inch side requires 6 × 300 = 1800 pixels. Submitting images at lower resolutions will result in visible pixelation, blurriness, and soft edges in your prints. Our tool resizes your photos to exactly 1200×1800 pixels for guaranteed print-ready quality.
Step-by-Step: Resize and Print a 4×6 Photo
Step 1: Choose your best photo — Select a high-resolution image. Most modern smartphone cameras produce 12-48 megapixel photos, which are more than enough resolution for 4×6 printing. Step 2: Check the fit — If your image is not already in a 2:3 aspect ratio, the tool adds background space so the full photo remains visible. Use our image cropper first only if you intentionally want to trim it. Step 3: Upload and resize — Drag and drop your photo into ImageGates and click "Resize to 4×6 (1200×1800 px)". Batch processing is supported for multiple photos. Step 4: Download and print — Save your resized image and upload it to your preferred printing service, or print at home on 4×6 photo paper.
4×6 Aspect Ratio Explained
The 4×6 format uses a 2:3 aspect ratio — the same ratio used by most DSLR cameras and many smartphone cameras. Images with another ratio remain fully visible and receive background space on two sides instead of being cropped.
Other Common Print Sizes
While 4×6 is the most popular, other common print sizes include: 2×2 inches — Passport and ID photos. Use our 2×2 resizer. 5×7 inches — A slightly larger print, popular for framed photos and greeting cards. Use our custom image resizer set to 1500×2100 pixels. 8×10 inches — The standard for framed wall prints and professional portraits. Set to 2400×3000 pixels at 300 DPI. For web and social media dimensions instead of print, check our tools for Instagram, Facebook, and YouTube thumbnails.
Tips for Best Print Quality
Start with the highest resolution — Never upscale a small image to 1200×1800. The print will look blurry. Use the original camera file whenever possible. Use sRGB color space — Most photo printers expect sRGB images. If your photo was taken in AdobeRGB or ProPhoto, convert to sRGB first for accurate color reproduction. Avoid heavy compression — If you need to email the resized photo before printing, compress to 500KB maximum. Higher compression will introduce visible artifacts in prints.
4×6 Photo Printing Guide
The 4×6 inch photo is the universal standard for photo prints. Whether you're printing vacation photos, family portraits, or event photography, this size fits standard frames and photo albums perfectly.
For best print quality, start with the highest resolution image you have. After resizing, you can compress the image if you need to email it, or convert to PNG for lossless quality. For other sizes, try our 2×2 resizer or custom resizer.

4×6 inch — print sheet for passport photos
4×6 inches is the standard photo-print size at any pharmacy or photo kiosk. Lay out two or four passport-size photos on one 4×6 sheet to print at home for a fraction of studio prices.
The 4 by 6 inch print, and what fits on it
You want a standard photo print size, or a sheet to cut identity photos from.
Four by six inches is the default print size at practically every photo counter and home printer in the world, and its three to two proportions match the shape of most camera sensors, which is why photographs fill it without awkward cropping. It is also the practical sheet for identity photographs: a single four by six print can hold six two inch squares or eight 35 by 45 millimetre photos, which is far cheaper than ordering them individually.
When people use this tool
Standard photo prints
The everyday print size for albums, frames and photo counters worldwide.
Identity photo sheets
Printing a grid of passport photos on one four by six sheet and cutting them apart.
Postcards and inserts
The size doubles as a postcard, a flyer insert or a product card.
Step-by-step
- 1 Upload your image. Start from the highest resolution version you have for the best print.
- 2 The 4 by 6 frame is applied. The picture is fitted to the print proportions without cropping the edges away.
- 3 Check the resolution. A good print needs around 1200 by 1800 pixels; less than that will look soft.
- 4 Download and print. Print borderless at the photo counter or at home on photo paper.

Practical tips
- • Print at 300 dots per inch where possible; 200 is the practical minimum before softness shows.
- • Ask for borderless printing if you want the image to run to the edge of the paper.
- • Phone photos in 4:3 do not exactly match 3:2, so expect a small margin or a small trim.
- • For identity photos, print on matte or glossy photo paper rather than plain office paper.
More questions about this tool
How many pixels do I need for a 4 by 6 print?
1200 by 1800 at 300 dots per inch. Around 800 by 1200 is the lowest that still looks acceptable.
Is 4 by 6 the same as 10 by 15 centimetres?
Effectively yes. 10 by 15 centimetres is the metric equivalent used in most of Europe.
Why is part of my photo cut off when printing?
Your image ratio does not match 3:2. Fitting it inside the frame leaves a margin instead of trimming.
Can I print passport photos at home?
Yes, on photo paper at the correct scale. Check your printer is not scaling the page to fit.
