The dimensions of a full-size ATX motherboard are 305 X 244mm that is ideal for several applications.

It serves as an ultimate option for gamers and workstations; however, this option is slightly expensive compared to other variants.

ATX is the largest and the widely-used form factor that comes with four memory slots.

The maximum dimensions of the Micro ATX motherboard are 9.6 X 9.6 inches.

Do you know that it was originally designed to be backward-compatible with ATX?

The mounting points used on the microATX are the subset of those used on the standard ATX boards, and hence, these can be used in full-size ATX cases without any hassle.
