BMW Badge Sizes Explained: 74mm vs 82mm — Full Fitment Chart
BMW has quietly used two rear roundel sizes for thirty years — 74mm and 82mm — and ordering the wrong one is the most common badge-upgrade mistake. This is the complete chart.

WHY Why size matters
The roundel seats into a recess with two alignment pin holes. Order wrong and the new badge either swims in the recess or won't seat flat — and adhesive won't save a bad fit. That's why HALO ships as one unit that fits both sizes: nothing to measure, no wrong orders, no returns.
HALO fits both 74mm and 82mm BMW rear badges — one unit, nothing to measure. A real-time animated screen where your roundel used to be.

How do I measure my badge without removing it?
Hold a ruler flat across the widest point of the roundel. 74mm ≈ 2.9 inches; 82mm ≈ 3.2 inches. The difference is visible once you know to look.
Does HALO fit the front/hood badge?
Not yet — HALO is rear-only today. A front/hood version is in development.
What about M badges or non-roundel trims?
HALO replaces the round factory roundel only. M-specific trunk badges are a separate mounting standard.
