[header] How to create a custom business card using photoshop [title] Create a template with the right specifications. [step] Open a new image in photoshop and set the width and height to 3.75 and 2.25 inches respectively. Set the resolution to 200 pixels/inch or more. 
The final size of your card will be 3.5 x 2 inches but it is customary to include a 1/8th inch' bleed area' all around, hence the slightly larger image above. The bleed area makes sure that the colours " bleed " out over the edges when the cards are cut, instead of leaving white borders.
