Text that works.
WHAT AFFECTS READABILITY
Size, which is usually too small Line length, which is usually too long Line spacing Contrast against the background
PRACTICAL GUIDANCE
Body text around sixteen pixels or larger Line length of sixty to eighty characters Generous line spacing Strong contrast
WHAT MOST SITES GET WRONG
Text too small and too light.
Light grey on white looks refined and is difficult to read, particularly outdoors or for older readers.
LOADING FONTS
Fonts loaded from another server add requests and delay.
Hosting fonts on your own server is faster.
Many themes and plugins offer a local hosting option.
HOW MANY FONTS
Two at most. One is frequently enough.
Each additional weight and style is another file.
WHAT TO TEST
Your site on a phone, outdoors, in daylight.
That is the condition most Nigerian visitors read in.
FOR ACCESSIBILITY
Contrast against the guidelines, not against your judgement.
