What is the best calculator for pcb design?

[Shahriar sakib]

hello sir,
Can you tell me which is the best calculator for PCB design? When I design a PCB, I have to fix my design rules. When I design a PCB, I have to decide what is the via size , what is the drill size of my PCB.
So, how do I calculate what are the appropriate parameters for my PCB?

One of the industry standards is the Saturn PCB toolkit https://saturnpcb.com/saturn-pcb-toolkit/
And the YouTube video https://www.youtube.com/watch?v=fJCRrEf_IH8&pp=sAQA

I agree with qdrives, Saturn PCB Toolkit is a really useful calculator.

About VIA or drill size, the smallest what I normally use are:
- if I would like to create a cheap PCB then minimum is usally 0.6mm pad size / 0.3mm hole,
- if I do not have space on PCB and I can use more expensive PCB, then it is usually 0.45mm pad size / 0.2mm drill size

This may explain why:

Thank you for sharing the information, sir. Actually I am learning pcb design. I am copying some pcb design exemple. So it was very important to know all this information.
