How to figure out the default font-size?

What if I don't set any specific font-size for a heading, how do I find out what the relative margin to the heading is? Is there a default font-size for h1, h2, h3, etc.?

Thank you.

Hello, Ermin! If you do not set a font-size, 16px is the default that the browser will implent.

The actual size depends on the browser and/or CSS, but here are some approximations:

H1  32px     
H2  24px
H3  18px    
H4  16px  (also plain inline text)
H5  13px
H6  10px

It depends on the browser, but inspecting the element using developer tools can be helpful.
