Pixelated or blurry photos are definitely big letdowns when you see your final prints. So please make sure that your photos have the required resolution for the size you have chosen.
The measurements above are an approximate of the final sizes in cm.
If you want an accurate measurement, multiply the inches by 25.4 to get the precise size in cm.
For example:
12 inches = 12 * 25.4 = 305 mm
The resolution requirements quoted are the minimum requirements needed. They are calculated at 72DPI.
If you want the best result, or if you are a professional photographer, we'd recommend at least 200 and ideally 300 DPI.
To calculate the accurate resolution requirement, multiply the inches by the DPI.
For example:
12 inches at 300 DPI = 12 * 300 = 3600px
8x10 inches = 20x25cm
12x12 inches = 30x30cm
16x16 inches = 40x40cm
16x20 inches = 40x48cm
18x24 inches = 45x60cm
24x36 inches = 60x91cm
