Appendix B: Choosing Image Dimensions
Table 18 provides the recommended maximum image dimensions (in pixels) you should use for each item layout so that students can view the item’s content on a standard 1024×768 monitor. For item layouts that include stimuli, the last two table columns provide maximum stimulus image dimensions.
These dimensions should not be regarded as absolute restrictions, but as guidelines to consider when inserting images in IAT.
The Compound layout is deprecated. Other layouts not listed here include GTR (Guide to Revision), Instructions, and Tutorial, none of which appear as standard items on a test.
