Keyboards are described by layout, and layout is a key count, not a measurement. Two boards both called 65% can differ by a meaningful amount across the case because of bezel style, side profile and whether the case is plastic or machined aluminium. So the method here is measure first, and use the layout only to sanity check what you measured.
What layout names actually tell you
| Layout | Approximate key count | What it implies for the box |
|---|---|---|
| Full size | About 104 | Longest footprint, numpad on the right |
| 1800 or 96% | About 96 to 100 | Numpad retained but compressed, shorter than full size |
| Tenkeyless | About 87 | Numpad removed, roughly the width of the alphas plus navigation |
| 75% | About 82 to 84 | Function row kept, navigation column compressed |
| 65% | About 66 to 68 | No function row, arrows retained |
| 60% | About 61 | Smallest common full alpha layout |
Use the table to know roughly what you are dealing with. Do not use it to derive a box size, because case dimensions for the same layout vary by model.
The measuring sequence
- Width. Across the case at its widest point, including any side lip, bumper or decorative badge. Not across the keycaps.
- Depth. Front edge to back edge of the case, again including any overhang.
- Height, feet down. Bench surface to the top of the tallest keycap, usually the function row or the escape key, with the feet folded flat.
- Height, feet up. Take this too if the board ships fully assembled, because a raised foot is a pressure point against the lid.
- Weight. Aluminium and gasket mounted boards are heavy for their size, and weight drives the board grade more than dimensions do.
Add roughly 1/8 to 1/4 in of clearance in each axis if the board sits in a foam or pulp tray, and more if it sits loose. State the result as internal length x width x depth.
Accessories are usually the problem
A bare keyboard is a simple shape. A keyboard kit is not. A braided detachable cable coils into a surprisingly thick disc. A wrist rest is often as deep as the board and adds its full thickness to the pack. A spare keycap set in a blister will not fold. Lay every item out in the arrangement you intend to ship, measure that arrangement, and size the box to it. If the accessories sit in a lower tier under the board, the box gets deeper rather than wider, which is usually the cheaper outcome.
Retail box or mailer, and why it matters for sizing
A retail keyboard box is a printed display item that will itself be shipped inside a master case, so it can be close fitting. A direct to consumer mailer has to survive the courier on its own, which means either a stronger board or a second box around the first. Double boxing changes your dimensions twice over, so decide the route before you draw anything.
Minimum, price and turnaround
Keyboard boxes start at 100 units, from about $0.48 per unit at bulk volumes, confirmed on your written quote. The cutting die, the printing plates, design support, US shipping and a digital proof are included, so a box cut to your exact case dimensions costs no more to tool than a near standard size. Turnaround is stated per product in three lanes, rush (expedited production plus air freight), standard (air) and cost saver (sea), from about 7 business days of production plus 2 to 5 days for delivery. Production runs from West Chicago in the US and Guangzhou in China.
Send the case measurements, the weight and a list of what ships alongside the board, and we will draw the tray and the box together. Start at request a quote, or order from the custom keyboard boxes page. If you are choosing between formats rather than measuring, see what size keyboard box do I need.
