# Dimensions
You can define your item dimensions using pixels (px) or percentage (%). Input a numerical value in the box or select from preset dimensions such as "auto" or "100%".
### Width
\- Auto: The item's width adjusts dynamically based on its content, expanding or contracting as required.
\- 100%: This width setting means the item spans the entire screen horizontally. For instance, setting it to 50% would occupy half of the screen's width.
### Height
\- Auto: When set to "auto," the item's height adapts dynamically to its content. For images, this usually maintains the original aspect ratio.
\- 100%: Specifying "100%" height fills the available vertical space within its container. For images, this may distort the aspect ratio if not maintained properly.
