What are the most common font-sizes for H1-H6 tags [closed]

Question

I've always been unsure of where to start as a general best practice baseline. Yes, I know it depends on your design, but what's most common?

Here's what I currently have as a starter:

h1 { font-size: 24px;} h2 { font-size: 22px;} h3 { font-size: 18px;} h4 { font-size: 16px;} h5 { font-size: 12px;} h6 { font-size: 10px;} 

Yes, we don't use EMs at my current job.

It would depend on the browser's default stylesheet. You can view an (unofficial) table of CSS2.1 User Agent stylesheet defaults here.

Based on the page listed above, the default sizes look something like this:

    IE7     IE8     FF2         FF3         Opera   Safari 3.1 H1  24pt    2em     32px        32px        32px    32px        H2  18pt    1.5em   24px        24px        24px    24px H3  13.55pt 1.17em  18.7333px   18.7167px   18px    19px H4  n/a     n/a     n/a         n/a         n/a     n/a H5  10pt    0.83em  13.2667px   13.2833px   13px    13px H6  7.55pt  0.67em  10.7333px   10.7167px   10px    11px 

Nowadays, all modern browsers have the same values as defaults.
