Subject: Border width for regions on a map/chart
No previous message | Next message →

Hi all.

I think this topic has came up in the past. After a few colors, it grows
difficult to maintain a good contrast. One way to offset that is to have a
strong border between sections, both in color and thickness. If my memory
serves me correctly, the conversation broke down after it got to 2, 5, 10,
and 10+ pixels.

Personally I am in the 5-10px range, but the individual wants a source.

Thanks

The Understanding page for WCAG 1.4.11 contains lots of explanations and examples, but it does not specify a minimum border width. In fact, some of the examples of textboxes have a border width of just one pixel. I am 100% certain that the minimum border width is not specified anywhere in any authoritative source.

In practice, I find that 3 pixels is usually enough, and I get a lot of push-back from designers and other stakeholders if I ask for anything wider. The same applies to focus indicators.

Thanks for the reminder. It took me to process the difference between fig 6
and 7. The second row of fig 6 passes, and the first row of fig 7 doesn't
is because 6's border gets a hair thicker when the star gets selected. The
pie chart was insightful, and should be able to give me footing I need.
