 For Eurorack the height is **3U, 128.5mm**.
-Note: The height of the PCB behind this is typically **110mm** giving 9.25mm clearance top and bottom to allow for rack mounts.
+==== PCBs ====
+The maximum height of the PCB behind this is typically **110mm** giving 9.25mm clearance top and bottom to allow for rack mounts, although 100mm is often used, especially if the PCB is going to a manufacturer such as JLCPCB.
+The width can be calculated as: **(HP x 5.08) - 0.34** to allow for side clearance.
