Image Gallery Thumbnail Dimensions

You enter thumbnail dimensions in the Width and Height fields on the Image Gallery Settings Basic tab.

 

Thumbnail dimension requirements depend on the gallery style you select. For Cropped, Hover Effect, Mosaic, and Mosaic Tight gallery styles you can enter either the width or the height dimension, and the other value will be set automatically to the value you enter so that the resulting thumbnail is square.

For Uncropped and Shadowed gallery styles, you can enter both width and height dimensions. Optionally, you can enter either the width or the height dimension and the other dimension will be automatically calculated.

If you enter both width and height, the system determines the best thumbnail size based on your entries. For example, you enter dimensions for a width of 150 and a height of 100. The dimensions of the image are 1920 x 1080. The system first calculates proportional dimensions based on the maximum width of 150 px. The calculated thumbnail height is 84 px which is less than the entered height of 100. Next the system calculates the dimensions based on the height of 100 px. The calculated width is 178 px. Since this is greater than the maximum width of 150 that you entered, the system uses the 150 x 84 dimension for the thumbnail.
