What mirroring gets right and what it gets wrong
Mirroring the layout is the right starting point. Reading order, navigation, progress indicators, sliders, back and forward arrows, and the placement of primary actions all reverse. But mirroring is a rule with exceptions. Media controls such as play and rewind usually keep their direction. Charts with a time axis often stay left to right. Phone dials, clocks and many logos do not mirror at all.
We keep a written exceptions list for every product so designers and developers apply the same judgment. Icons need a case-by-case check: a mirrored arrow is correct, a mirrored check mark or a mirrored letter is wrong. The audit stage finds these one by one in your existing screens and gives each fix a priority, so a team with a live product can repair the worst problems before a full redesign.
