Buying mirrors online allows for a massive selection, but it requires careful planning to avoid the common pitfalls of poor fit, distorted glass, or shipping damage. 📏 1. Measuring & Sizing
A vanity mirror should be 2–4 inches narrower than the vanity itself.
For mirrors hung above furniture (like a console or sofa), the mirror should be roughly 2/3 to 3/4 the width of the piece below it.
If you want absolute color accuracy (no slight green tint at the edges), look for "low-iron" glass.
Before buying, tape a piece of cardboard or paper cut to the mirror's size on your wall to see how it feels in the space.
High-quality mirrors use a thick coating of silver-nitrate-compound on one side to ensure 80–90% light reflection.
