A very common question is how big are my images going to be. This is both a simple and a rather complex answer.
Images are generally sized differently if you are talking about “digital images” or “printed images”.
Digital images are typically sized in pixels, I often use the phrase “1800 on the long edge of the image” this means that whichever side of the image is longer will be sized at 1800 pixels and the other size will depend on the ratio of the image (often 3:2 or 5:4). One good example that you may have heard before is the size of a TV screen, an HD TV screen is normally 1920pixels wide x 1080pixels high (which has an aspect ratio of 16:9).
Printed images are more often sized in inches (or centimeters), 4x6inch(a 2:3 ratio) or 8x10inch(a 4:5 ratio) prints are common sizes and we need to be able to convert the digital pixel size to the printed size. for this we often use a term called “Pixels Per Inch” or “PPI” (not related at all to insurance protection).
This is where the waters can be muddied slightly, different printing methods use different PPI’s a “traditional” printed photo would normally be 300ppi, so an 8×10 inch print would need 2400x3000pixels, some canvas prints can be lower than this but each one will have it’s own specific requirements that you will need to check before purchasing a digital image.
