Image Size and Unit

The top fields will allow you to set the size in pixels and the bottom field will allow you to set the size in a arbitrary length unit. The difference between the two of them is that if you specify the the size in e.g inches then the size in pixels is dependent of the image resolution. I.e if you decrease the default resolution you will decrease the size in pixels but not the real size measured in e.g inches.

Image Resolution and Resolution Unit

Let you set the default image resolution and resolution unit. The default image resolution is always measured in dpi (ppi) while the default resolution type is arbitrary. However Gimp lets you set the default resolution in your arbitrary resolution unit in the two bottom fields.

Image Type

Lets you set what type of image you want to create by default either RGB or Grayscale.

Summary

Does the size & unit contra resolution image/unit sound a bit complicated and hard to understand? Let us give you an example. You are familiar with the metric system but as most designers you are more familiar with a resolution based on pixels per inch (ppi or dpi). Then you have to set image unit to millimeters (or centimeters) while you will set the resolution unit to pixels/inch. This will give you the comfort of working with two familiar units in this case size measured in the metric system and resolution measured in ppi. As default values that you have to set i.e size in this case millimeters and the resolution in ppi is up to you and what type of work you are involved in.
