Half a millimeter is the thickness you reach for when the heatsink almost touches the chip already. On graphics cards it is the VRAM gap on a well-machined cooler, on laptops it is the strip between a copper spreader and a controller IC, and on an M.2 drive it is everything between the NAND and the motherboard shield. This 80 x 40 mm sheet of GP-Extreme carries 12 W/mK through that gap without adding height the cooler cannot absorb.
Where half a millimeter is the right answer
A 0.5 mm pad exists for surfaces that are nearly coplanar. Reference-design graphics cards, thin-and-light notebook boards and NVMe drives under a motherboard shield all fall into that band. The rule of thumb worth keeping is simple: measure the gap, then pick the pad that fills it with a light squeeze rather than one that forces the heatsink to sit proud of its mounting posts.
Reading the 80 x 40 mm sheet before you cut
The sheet gives you 3,200 square millimeters to work with, which on most cards is enough for a full row of memory packages plus a couple of spare offcuts. Lay the cooler plate down, mark the contact islands with a pencil on the protective film, and cut on a self-healing mat with a fresh blade. Cutting through the film keeps the pad clean and stops the edges rolling under the knife.
Handling a pad this thin without tearing it
Thin pads are the ones people ruin. Peel one liner at a time, keep the second liner in place while you position the piece, and lift by the film rather than the compound. If a strip stretches out of shape it will not recover, because 12 W/mK filler is loaded with conductive particles and behaves more like soft clay than rubber. Work slowly and a 0.5 mm piece will go down flat on the first attempt.
What one sheet realistically covers
For a single mid-range graphics card teardown, one sheet usually covers the memory row and the small inductor islands with material left over. For a laptop refresh it is generous. The compound does not cure or dry out, so offcuts stored between their liners in a sealed bag stay usable for the next job rather than turning brittle on the shelf.
