🧮 How to Calculate A7 Size in Pixels
The formula to convert A7 paper size (74 × 105 mm) to pixels is simple:
🔢 Conversion Formula
Width in pixels: Width (px) = 74 × (DPI ÷ 25.4)
Height in pixels: Height (px) = 105 × (DPI ÷ 25.4)
Total pixels (megapixels): MP = (Width × Height) ÷ 1,000,000
Example: At 300 DPI: Width = 74 × (300 ÷ 25.4) = 874 px | Height = 105 × (300 ÷ 25.4) = 1,240 px
The constant 25.4 is the number of millimeters in one inch, which converts mm to inches before multiplying by the DPI value.
