1,200 × 1,800 pixels in inches at every common resolution
The physical size depends entirely on the density you print or display at — these are the values people look up most.
| Resolution | Width × height in inches | In centimetres |
|---|---|---|
| 72 PPI | 16.667 × 25 | 42.333 × 63.5 |
| 96 PPI | 12.5 × 18.75 | 31.75 × 47.625 |
| 150 PPI | 8 × 12 | 20.32 × 30.48 |
| 300 PPI | 4 × 6 | 10.16 × 15.24 |
| 600 PPI | 2 × 3 | 5.08 × 7.62 |
How the conversion works
Inches are found by dividing the pixel count by the pixel density: inches = pixels ÷ PPI. For 1,200 × 1,800 pixels at 96 PPI that is 1,200 ÷ 96 = 12.5 and 1,800 ÷ 96 = 18.75.
1,200 × 1,800 is exactly a 4 × 6 photo print at 300 DPI.
Printed at 300 DPI it covers 4 × 6 inches; on a 96 PPI screen the same pixels span 12.5 × 18.75 inches.
That is 2.16 megapixels in total, in 2:3 proportion. In metric the 300 DPI print measures 10.16 × 15.24 cm.
Frequently asked questions
How many inches is 1,200 × 1,800 pixels, a 4 × 6 photo print at 300 DPI?
12.5 × 18.75 inches at 96 PPI, 8 × 12 inches at 150 DPI and 4 × 6 inches at 300 DPI. Divide the pixels by the density you are using.
What size does 1,200 × 1,800 pixels print at 300 DPI?
4 × 6 inches, which is 10.16 × 15.24 cm. 300 DPI is the standard for photo and magazine printing.
What is 1,200 × 1,800 pixels in centimetres?
31.75 × 47.625 cm at 96 PPI, or 10.16 × 15.24 cm at 300 DPI.
Should these pixels be printed at 300 DPI?
Yes, if the print is held or read close up. At 300 DPI they cover 4 × 6 inches, which is what that standard is for. At 150 DPI the same pixels stretch to 8 × 12 inches and the softening shows in the hand.
Is 1,200 × 1,800 a 2:3 ratio?
Yes, and 2:3 is the shape of a 4 × 6 print, so it fills one edge to edge with nothing cropped.
What is the largest standard print 1,200 × 1,800 pixels will make at 300 DPI?
A 4 × 6 photo print. 2.2 megapixels is 4 × 6 inches at 300 DPI, which covers a 4 × 6 photo print with the rest as margin or crop.
