In the N panel there is an option to view edge lengths. (also face area and angles)
Is there somewhere in the preferences where this text size can be increased? It is exceptionally small and difficult to read on a high res monitor.
If a size adjustment is not possible, can the offset be set so that it is moved a bit further away from the line? (Often it is right on the line and this also makes it difficult to read at times.
@JA12, thanks for pointing out that the color could be changed. Although I’m with rcpongo in that being able to change the text size would be useful, changing to a bright color definitely helps, as shown in the screen shots.
go to user preference interface
at top left there is scale for text all over
and this will increase all text shown on your screen including
edge length in 3D viewport
but at maximum scale it makes everything larger on your screen
and might not be the best option hard to find things!
My previous attempt to reply went sideways, so I’ll try again.
From Blender’s File menu choose User Preferences and switch to the Themes tab. As shown in the attached screen shot, you can change the color of the edge length to your liking.
