To choose a wrist rest for a 68-key keyboard, start with your keyboard's real measurements, not its key count. "68-key" describes the layout, but it doesn't tell you how wide or deep the case is. Measure the case width across the front edge and its front-to-back depth, then compare those numbers with the rest you're considering.
Next, make sure the rest fits in the free space in front of your keyboard. Then set it in place and judge whether its contact height suits you.
Measure and compare the actual dimensions
Two numbers from each item do most of the work: width and front-to-back depth. Take them from your actual keyboard and the actual rest, not from a layout name.
Measure the keyboard and wrist rest
You need four measurements in total, two for each item:
- Keyboard width: Measure across the front edge of the case, from the left side to the right side. Measure the case itself, not just the rows of keys.
- Keyboard depth: Measure from the front of the case to the back.
- Wrist rest width and depth: Find both in the product listing, or measure the rest side to side and front to back if you already have it.
- One unit for everything: Inches work well. If a listing uses centimeters, divide by 2.54 to convert.
Compare width and depth for their different jobs
Width tells you whether the rest lines up with the keyboard. OSHA's front-edge width guidance says a wrist rest should match the front edge of the keyboard in width. So the number to compare is your rest's width against your board's front-edge width. The 68-key label can't stand in for that check.
Depth works differently. The rest and keyboard don't need to be equally deep. Instead, add the two depths to see how much desk depth the whole setup takes. As an illustrative example, a keyboard 4.5 inches deep plus a rest 3 inches deep needs about 7.5 inches of front-to-back space. For the rest itself, OSHA's checklist calls for at least 1.5 inches of depth, measured away from the keyboard. Use that as a reference point when you compare candidates, not as proof that a rest fits your board.
If you also use a 60%, 75%, or TKL board, our keyboard wrist rest fit guide covers those sizes too.
Check the space in front of the keyboard
A keyboard wrist rest only works if it fits where your keyboard actually sits. Check the clear area in front of the board before you decide:
- Put the keyboard in its normal typing position, where you really use it.
- Measure from the keyboard's front edge to the edge of the desk or tray. That clear depth needs to be at least as deep as the rest.
- Place the rest directly in front of the keyboard. If you don't have it yet, cut a piece of paper to its width and depth and lay that down instead.
- Check that your mouse, mouse pad, and anything else you need still have room, and that you didn't have to push the keyboard back to make space.

If the rest crowds your gear, look for a shallower one, or move the keyboard back if your desk allows it. Keyboard trays need extra care. OSHA's keyboard-tray space guidance says trays should be wide and deep enough for the keyboard and any peripheral devices, such as a mouse. On a tray, the rest has to fit on that same surface, so measure the tray's usable depth, not the desk's.
Once you know your clear depth, you can compare wrist rest options by their listed depth. If your whole desk is tight, our guide to keyboard layouts for small desks shows how to measure for mouse room.
Choose a contact height that works in your setup
Pick the rest whose top surface sits closest to your keyboard's front edge and feels right when you try it. OSHA's front-edge height guidance recommends matching the wrist rest to the keyboard's front edge in height, slope, and contour.
To check this, set the rest against the keyboard in its usual spot. Look at the pair from the side. Compare the top of the rest with the top of the case's front edge. Note whether the rest is flat or slopes, and whether its edge follows the shape of the case.
Then rest your hands on it the way you would during a pause in typing. Some people prefer a contact point a bit lower, and others prefer it level with the case. Your preference is what decides it. If the rest sits clearly higher or lower than you like, or its edge doesn't line up with the case, keep looking.
Your chair and desk height also change where your hands land. Our gaming desk setup tips cover those pieces if you want to adjust the rest of your setup.
FAQs
What if I can't find my keyboard's dimensions?
Measure it yourself with a ruler or tape measure. Measure the case across the front edge and from front to back, and write both down in inches. If you're shopping from a listing that gives centimeters, convert it so your numbers match.
Should my wrists stay on the rest while I type?
OSHA's checklist says wrist rests were designed for resting, and their use should be kept to a minimum while you're actively typing. In practice, that means using the rest during pauses rather than planting your wrists on it for every keystroke.
What pad material does OSHA suggest?
The same OSHA checklist says the pad should be soft but firm, and it recommends gel-type materials. If you're weighing harder materials, compare them against that description and against your own comfort. Your width, depth, and height checks still decide whether a rest fits.
