There are two values that can be used to set font size - pixels (px) and points (pt). These values are not equal - for example, a font size of 10pt is 13px.
You may need to work out the equivalent value for your font sizes, for example if you know that your text needs to be a certain px, but your mail client uses pt.
For more information on applying font sizes, see How to use pixel and point values in font sizing.
We recommend! Common font sizes:
- 11pt - 12pt for larger text
- 10pt - 8pt for contact details
- 8pt - 7pt for disclaimers
The following table displays the value equivalence between pixels and points.
This means that if you set a pixel value of, for example, 15px, and Microsoft Outlook uses points, your text will display at 11pt.
| Pixel value | Point value | Typical size rating |
| 8px | 6pt | |
| 9px | 7pt | |
| 10px | 7.5pt | x-small |
| 11px | 8pt | |
| 12px | 9pt | |
| 13px | 10pt | small |
| 14px | 10.5pt | |
| 15px | 11pt | |
| 16px | 12pt | medium |
| 17px | 13pt | |
| 18px | 13.5pt | large |
| 19px | 14pt | |
| 20px | 14.5pt | |
| 21px | 15pt | |
| 22px | 16pt | |
| 23px | 17pt | |
| 24px | 18pt | x-large |
| 26px | 20pt | |
| 29px | 22pt | |
| 32px | 24pt | xx-large |
For values outside of this table, use the following conversion:
1.33px = 1pt
For example, 19pt = 25px (rounded to the nearest whole value).
