Hand-picked for this exact result — no generic lists.

A standard jewel case is 14.2 × 12.5 × 1.05 cm — a Kallax cube fits a single neat row of them.

Separate your case types.
Jewel cases, slim cases and digipaks have very different thickness — measure each stack.
Count spines, not discs.
Multi-disc sets in fat cases count as one thick item.
Leave flipping room.
A 5% allowance keeps the row browsable instead of wedged.
Mind the depth.
CDs are only ~14 cm deep in a 39 cm cube — push them flush to the front.

One concrete case, with the assumptions spelled out.

At 1.05 cm per case, one cube holds about 30 CDs. Eight cubes give 240 CDs.

ƒ(x)per cube = floor(33 ÷ (thickness × (1 + allowance ÷ 100)))
