# A tip on resizing

Just a tip on resizing photos etc. This formula was given to me years ago when document resizing first came to the photocopying community. If you want to reduce or enlarge a photo/document to a specific size use the formula acronym DOOR. This translates to Desired Over Original. To get a 50% reduction a lot of people think that you need to reduce the item by 50% not so; you need to reduce the item to 70% of the original. Look at it this way an area of 100 square units would be made up from 10 X 10 units, reducing it to 70% gives you 7 X 7 units which when multiplied out gives 49 Square units. 10 x 10 = 100, 7 X 7 = 49 roughly 50%. The formula works for reduction and enlargement but is, as you will have noticed not exact.
To achieve a resize of 380 pixels from 413 using the above formula you divide 380 by 413 to give a required reduction of 92%.
