Motherboard Sizes Comparison Guide – TheBestMotherboard

If you are building a computer yourself, you should know the differences between the different sizes of motherboards available. My first PC was a disaster as a result of not knowing that when I built it many years ago.

With today’s motherboard size comparison chart, I’ll help you figure out what the different motherboard sizes are and how they compare.

The article will give us more details in regards to this subject, however, let’s begin by presenting you with the main comparison chart you came here for motherboard sizes.

Motherboard Size Height Width
ATX 12 inches 9.6 inches
Micro-ATX 9.6 inches 9.6 inches
Mini-ATX 11.2 inches 8.2 inches
E-ATX 12 inches 13 inches
Flex-ATX 9 inches 7.5 inches
WTX 14 inches 16.75 inches

ATX (Advanced Technology Extended motherboard)

On the PC motherboard, it replaced the Baby AT design. Due to its ATX layout, there is room for full-length expansions to be installed in all sockets of the CPU and memory. Instead of pulling air through the chassis, the power supply blows air over the CPU.

As the first PC motherboard to incorporate serial, parallel, mouse, and other I/O ports directly onto the motherboard, the ATX was introduced in 1995. Prior to the ATX, the motherboard was equipped with only a keyboard connector.

In turn, a variety of variants with both smaller and larger form factors were introduced, including microATX, Mini ATX, FlexATX, and Extended ATX.

Motherboards Form Factors

Micro ATX

A few centimetres can be reduced from the length and width of an ATX motherboard. You sometimes have to sacrifice some slots as well when you have a smaller size and build.

When you buy the highest-end models, you will see similar specs like 4 RAM slots, which is the case with ATX motherboards. As compared to other larger sizes, you will also find fewer PCIe slots on mATX motherboards.

However, the only drawback is that there is less room for future expansion than with ATX motherboards, even though you get most of the same features. Today, the mATX motherboards on the market feature similar hardware components to the ATX ones.

The mATX motherboards are less expensive since they have a smaller size and fewer ports. Furthermore, you can use these types of motherboards with smaller PC cases because of their compact size.

Mini ATX

By just looking at the name of these motherboards, you can pretty much guess their size. There are actually only two types of mini-ITX boards out there that can be equipped with standard-sized hardware components.

In terms of size, these motherboards tend to be the smallest, generally being 6.7 inches by 6.7 inches. Despite this, it is very rare for larger VRMs and heatsinks to be available.

The motherboard cannot have more than two RAM slots due to its small form factor. Besides, a mini-ITX can’t support more than one GPU, so building a multi-GPU setup is hard.

The power delivery on the majority of mini-ITX motherboards is also not great due to their 4 pin connectors. In most cases, such builds make overclocking dreams impossible. Mini-ITX boards are inexpensive and can easily fit within a small-sized PC case, but their main advantage is that they are small and can be easily integrated.

E-ATX

(Extended ATX) ATX motherboard that extends into a 13″ rather than 9.6″ length.

Motherboard Size Guide

Conclusion

Now that you know a bit about each type of motherboard, we hope you have a good idea about them. An expansion slot and other connections are usually paid for when you purchase a motherboard. The reason why larger motherboards with more ports are more expensive than smaller ones with fewer ports is because of their size.

In case you are going to build a powerful PC and wish to utilize multiple GPUs, and EATX or ATX motherboard will be the best option. Alternatively, if you want to build a more compact PC or you have a limited budget, you can choose between mATX and mini-ITX motherboards. In the comments section below, you can discuss any other motherboard-related questions you may have.
