127 × 178 mm is a portrait 5:7 format (5 × 7.01 in). To print it sharply, the image needs about 1500 × 2102 pixels, which is 3.2 megapixels.

This size corresponds to 5R photo print (5 × 7 in).

127 × 178 mm in pixels

Pixels = size in inches × DPI. DPI is a printing instruction, not a quality setting: it says how many pixels are spread over each inch of paper. With the DPI field on Auto, ResizeAny converts at 96 DPI, which suits screens. For print, set 300 DPI. JPG and PNG output stores the DPI value in the file.

DPI	Use	Pixel size
72	Screen preview	360 × 505
96	Tool default (Auto)	480 × 673
150	Large posters, viewed from a distance	750 × 1051
300	Photos, cards, anything held close	1500 × 2102

Will your photo be sharp enough?

A 12-megapixel phone photo (4000 × 3000) has more than the 1500 × 2102 pixels this size needs at 300 DPI, so it can be printed sharply with room left to crop.

Needed source resolution: 3.2 megapixels or more at 300 DPI.

Matching the 5:7 shape

The output is 5:7. If your photo has another shape, it has to be cropped or it will be stretched. This is how much of each common photo is lost when cropped to fill 5:7:

Starting photo	Cropped away to fill the shape
Phone photo (4000 × 3000, 4:3)	About 46% of the image
DSLR photo (6000 × 4000, 3:2)	About 52% of the image
Video frame (1920 × 1080, 16:9)	About 60% of the image
Portrait phone photo (3000 × 4000, 3:4)	About 5% of the image

How to resize an image for wedding invitation (rectangle)

Add your image. Select a photo or drag it onto the box above. JPG, PNG, WebP, AVIF, HEIC and BMP files are accepted, and the file stays on your device.
Set the resolution. The preset fills in 127 × 178 mm. Leave DPI on Auto to convert at 96 DPI, or enter 300 DPI for print so the file has enough pixels for a sharp result.
Crop if the shape differs. The target shape is 5:7. If your photo is a different shape, crop it first so the print is not stretched.
Download and print at 100%. Save as JPG or PNG; the DPI value is stored in the file. Print at 100% scale, not "fit to page", so the physical size stays exact.

Frequently asked questions

What is 127 × 178 mm in pixels?▼

It depends on DPI: 480 × 673 px at 96 DPI, 750 × 1051 px at 150 DPI and 1500 × 2102 px at 300 DPI.

What DPI should I use for a 127 × 178 mm print?▼

300 DPI for anything seen up close, such as photos, cards and labels; 150 DPI is acceptable for larger prints viewed from a distance. Higher than 300 rarely gives a visible gain.

What is 127 × 178 mm in other units?▼

5 × 7.01 in, 12.7 × 17.8 cm and 127 × 178 mm. It matches 5R photo print (5 × 7 in).

How do I make sure it prints at exactly 127 × 178 mm?▼

Set the size and a DPI, download the file, and print at 100% scale. Options such as "fit to page" or "shrink to printable area" silently change the physical size, so turn them off. If a lab does the printing, tell them the exact size rather than relying on the file's DPI value.

Is a phone photo big enough for 127 × 178 mm?▼

Yes. A 12-megapixel phone photo has more than the 3.2 MP needed at 300 DPI.

Do I need an account, and does it add a watermark?▼

No account and no watermark. Open the page, add your photo, and download the result. Because processing happens on your own device, there is no queue and nothing to wait for, even with a large original.
