Form Factors are the physical size and shape of a device. It is often used to describe the size of circuit boards. AKA - Motherboards
The Form Factor of a motherboard shows the specifications for its shape and size.

The form factor just describes the layout of the case, where everything is placed in the slots the at the back of the case, and the way that the case matches to the large, important components that fit into it. There are 3 main components that must be matched in terms of there form factor:
-The case,
-The power supply,
-The Motherboard.
Usually when you buy a system case it comes with a power supply so you dont have to match up with a case and power supply but if youre lucky some case form factors can work with more than one power supply form factor.
Form factor is important if you build your own computer systems because you need to make sure that your motherboard,case,power supply and form factors match!

In this picture, it just basically shows the different sizes and cases of the form factors.


Some mother bourd form factors include:
AT- which is similar to ATX and babyAT which is an original IBM PC Motherboard
and many more.
The sizes of each different type of mother board form factors can be found on this website given:

The most popular case form factors today are the
-Baby AT
and NLX, with the newer microATX/SFX form factor also being used increasingly on lower-end systems.
These cases are not interchangeable, since they are shaped differently, and require motherboards with a different form factor. There are cases that can handle both baby AT and ATX Motherboards.

The costof form factors may vary depedning on how big the motherboard size is and or which case you get. So they all come in different costs depending on what you want.
The microATX form factor for example was developed as a newer version of the ATX form factor to get new market trends and computer technologies. The same benefits of the ATX form factor, the microATX form factor improves on the one before specification in many key areas. Current trends in the industry show that users require a lower-cost solution for their computer needs. Without giving up the benefits of ATX, this form factor shows the cost requirement by reducing the size of the motherboard. The smaller motherboard is made possible by reducing the number of I/O slots supported on the board. The effect of these size changes lowers the costs associated with the entire system design. The expected effect of these reductions is to lower the total system cost to the end user.
