300 × 400 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.

How the conversion works

Inches are found by dividing the pixel count by the pixel density: inches = pixels ÷ PPI. For 300 × 400 pixels at 96 PPI that is 300 ÷ 96 = 3.125 and 400 ÷ 96 = 4.1667.

Printed at 300 DPI it covers 1 × 1.3333 inches.

At that size a print is held or read close up, where 300 DPI is the density to work to. On a 96 PPI screen the same pixels span 3.125 × 4.1667 inches.

That is 0.12 megapixels in total, in 3:4 proportion. In metric the 300 DPI print measures 2.54 × 3.3867 cm.

Frequently asked questions

How many inches is 300 × 400 pixels?

3.125 × 4.1667 inches at 96 PPI, 2 × 2.6667 inches at 150 DPI and 1 × 1.3333 inches at 300 DPI. Divide the pixels by the density you are using.

What size does 300 × 400 pixels print at 300 DPI?

1 × 1.3333 inches, which is 2.54 × 3.3867 cm. 300 DPI is the standard for photo and magazine printing.

What is 300 × 400 pixels in centimetres?

7.9375 × 10.583 cm at 96 PPI, or 2.54 × 3.3867 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 1 × 1.3333 inches, which is what that standard is for. At 150 DPI the same pixels stretch to 2 × 2.6667 inches and the softening shows in the hand.

Is 300 × 400 a 3:4 ratio?

Yes. That is 3:4, which is not a standard print shape: the closest is a Letter page, and fitting it means losing about 3% along the long edge.

What is the largest standard print 300 × 400 pixels will make at 300 DPI?

None of the common sizes — at 300 DPI it covers only 1 × 1.3333 inches, smaller than a 4 × 6. At 150 DPI it reaches 2 × 2.6667.
