Start with the deepest socket in each drive size. A ½-inch drive describes the square drive connection. It does not tell you the height of the loaded socket.

Measure usable clearance

1. Leave the liner in place. Measure vertically from the liner to the lowest obstruction above the socket’s path as the drawer closes.
2. Measure from the bottom of the organizer to the top of the tallest fully seated socket. Include any size stem that projects above it.
3. Compare those measurements. As a worked example, 80 mm of drawer clearance and a 76 mm loaded assembly leave 4 mm. Those numbers illustrate the calculation, not a Toolbox Widget product specification.
4. Test one row and close the drawer slowly. Account for drawer movement and any uneven liner before loading the rest.

When upright storage is the wrong choice

If a deep socket or label stem interferes, try a deeper drawer or horizontal storage. A portable rail can be more practical when you routinely take a whole set to a vehicle. Separate SAE and metric rows if the sets look similar.
