How many layers should I use in my PCB design?

While starting a project ,how should i decide the number of layers to use when designing my board. What are the best practice to consider before doing this.
Solution:
Depends on the complexity of the design, budget and signal interference. Usually if it’s a really simple board I’d do 2 layer and I usually do a 4 layer if it’s more complex.

That goes more into depth though

great, how about for microcontroller based design that require controlled impedence which should i use 2 or 4 layers

i suggest you use a four layers board when using an MCU and especially with controlled impedence, it helps to keep the traces smaller. And can also give your design better signal integrity.

Yea I would use 4 layers as well if there’s controlled impedance
