Desk Risers Sized to Your Desk Legs

Sit in your usual chair with your feet flat and your shoulders relaxed, and have someone measure from the floor to the underside of your forearms with your elbows bent at about ninety degrees. That number is your ideal desk surface height. Subtract your current desk height from it and you have your lift, to the quarter inch.

Take the measurement in the chair you actually use, at the seat height you actually use, because changing the chair changes the answer. A lift of one to three inches is the usual result for someone who finds their desk a little low. Turning a sitting desk into a standing desk is a different problem entirely and needs far more height than a riser under a desk leg should carry. Risers are for fine adjustment and moderate lifts.

Do not forget knee clearance and the keyboard tray. Raising a desk raises its underside too, which is normally welcome, but if you have a drawer pedestal or a tray already scraping your thighs, the lift fixes it; if you have a low bookshelf shoved underneath, check it will still slide out.

Desk legs fall into three families. Square or rectangular wooden posts, common on traditional and farmhouse desks, are the easiest: measure the footprint at floor level and add a quarter inch to each dimension. Flat panel or trestle-style ends, common on flat-pack desks, are wide but thin. A pair of small risers per end, or a long slot opening, suits those better than one square riser. Add the panel's length and thickness in the notes box.

Round steel tube legs, found on most budget and gaming desks, are measured by diameter and need a round opening, which you request in the notes. Many of these desks come with threaded leveling feet screwed into the tube. Measure whichever part will actually sit inside the riser, and if the leveling foot is adjustable, wind it fully in first so all four legs start from the same reference.

Because desks often sit on carpet, check the desk is level after the risers are in. It is much easier to correct a small wobble with the desk's own leveling feet than to reprint a riser.

A desk's load is quieter than a bed's or a sofa's but heavier than people guess. Monitors on an arm, a desktop tower, a dock, books and everything else stacked on the surface add up quickly. A monitor arm clamped to one edge matters most, because it puts a constant off-center pull on one corner rather than a share of the load on all four.

The upside is that a desk load is static, so a standard riser with a properly sized opening handles most setups. Add the reinforced build if you lean or sit on the desk edge, if you have a heavy stone or thick butcher-block top, or if the desk is loaded up heavily. Enter the loaded total in the weight field so it is recorded with your dimensions.
