Set your desk converter so its work surface sits about 1 to 2 inches below your elbow height when standing, with your forearms parallel to the floor and elbows near a 90 degree angle. For most adults that lands between 38 and 44 inches, but measure your own elbow height rather than trusting a fixed number.
- OSHA’s Computer Workstations guidance calls for elbows close to the body and forearms roughly parallel to the floor whether you’re sitting or standing.
- Most adults land between 38 and 44 inches for standing keyboard height, but your own elbow measurement overrides any chart.
- NIOSH research warns that standing still for long stretches carries its own risks, including low back pain and leg fatigue, so alternating with sitting matters as much as the height itself.
- A desk converter adds height on top of your existing desk, so measure from the floor to the converter’s keyboard tier, not the desk surface underneath it.
- Cornell’s ergonomics program notes the evidence for sit-stand furniture benefits is still limited on its own, which means setup quality matters more than the furniture itself.

The Quick Answer: Desk Converter Height by Your Height
A desk converter sits on top of a desk you already own, which is exactly why the setup trips people up. You’re not measuring from a fixed factory height like a full standing desk. You’re measuring from wherever your existing desk happens to sit, then adding the converter’s own range on top of that. Get the math wrong and you either can’t reach standing height at all, or the converter tops out too low for anyone over average height.
Most adults fall into a fairly narrow band, and this table is a starting point, not a final answer. Confirm it with the elbow check further down before you lock in a height.
| Your Height | Standing Keyboard Height | Standing Eye Level |
|---|---|---|
| Under 5’4″ | 36 to 39 inches | 58 to 62 inches |
| 5’4″ to 5’9″ | 39 to 42 inches | 62 to 66 inches |
| 5’9″ to 6’2″ | 42 to 45 inches | 66 to 70 inches |
| Over 6’2″ | 45 to 48 inches | Above 70 inches |
Why Converter Height Matters
OSHA’s Computer Workstations eTool keeps coming back to the same principle for any posture, sitting or standing: elbows close to your body, forearms roughly parallel to the floor (OSHA, Computer Workstations eTool: Positions). Set your converter’s keyboard tier above that line and you’re reaching up all day. Set it below, and your wrists cock upward with every keystroke.
Height isn’t the only variable, either. NIOSH’s research on prolonged standing found real risks tied to staying in one static posture too long, including low back pain and leg fatigue, not just from sitting (NIOSH, Prolonged Standing at Work). A desk converter that’s dialed in perfectly still won’t help much if you never lower it back down. The setup matters, but so does using it the way it’s meant to be used, switching between sitting and standing through the day instead of parking in one position for hours.
How to Measure Your Own Elbow Height
- Stand up straight and let your arms hang naturally at your sides.
- Bend your elbows to roughly 90 degrees, like you’re about to type.
- Measure straight down from the bottom of your forearm to the floor, with help or against a wall using a pencil mark.
- Write down that number. It’s your target standing keyboard height.
- Repeat the same check seated in your chair for the sitting height your converter needs to drop to.
A good desk converter should hit both numbers without you needing to prop it on books or shim it with anything.
How to Adjust Your Desk Converter to Reach It
Most converters adjust in one of two ways: a gas-spring lift you push or pull to a height, or a crank or motor with marked presets. Start by setting the keyboard tier to your standing elbow number from the last section. Sit down and check the same tier lands near your seated elbow height too, since a good converter should serve both positions without you having to readjust the whole desk underneath it.
If you’re shopping for one, our picks for standing desk converters for beginners cover models with simple, repeatable height presets, which matters more than it sounds like once you’re adjusting it several times a day. If you already know you want fine-grained height control, our picks for converters with adjustable height levels covers that specifically.
Setting Up the Monitor and Keyboard Tiers
A desk converter usually has two tiers, one for the keyboard and one for the monitor, and they need separate attention. Set the monitor tier so the top third of the screen sits at or just below eye level standing up, roughly the numbers in the table above. If your converter only has one flat platform, add a monitor riser or stack on top of it rather than setting the whole platform too high just to lift the screen. If you’re working from a laptop instead of a desktop, raise the laptop on its own small stand within the converter’s platform rather than typing on it directly at standing height, since a laptop’s built-in keyboard sits too close to the screen to work at that angle.
Cable length is the detail most people miss. A converter that travels 15 to 20 inches between its lowest and highest setting needs slack in every cable, power, monitor, and any dock, or you’ll yank a cord loose the first time you raise it. Route cables through a clip or sleeve that moves with the platform instead of anchoring them to the desk below.
Special Cases
Not everyone fits the standard chart, and a few situations need adjustment beyond the numbers above.
- Laptop users should add an external keyboard and mouse once the laptop is raised to standing eye level, since typing on a laptop’s built-in keyboard at that height forces your shoulders up.
- Dual monitor setups need the converter’s platform wide enough for both screens plus the keyboard tier below, which rules out some of the smaller single-monitor risers.
- Very tall or very short users, outside the roughly 5’0″ to 6’4″ range most converters are built for, may need a model with a wider adjustment range or a separate monitor arm instead of relying on the converter’s built-in monitor shelf.
- Shallow desks under about 24 inches deep need their footprint checked against the converter before buying, since some units need more depth than that to sit stable.
- Long standing sessions go better with an anti-fatigue mat, since a hard floor under your feet tends to shorten how long standing feels comfortable, regardless of how well the desk itself is set up.
Signs Your Setup Is Wrong
Wrist pain or numbness while typing standing usually means the keyboard tier is set above your elbow height, not below it. Shoulder shrugging by midday points to the same problem. Neck strain looking at the monitor is almost always a monitor tier set too low relative to your standing eye level, the opposite adjustment from the keyboard issue. And if your lower back aches by early afternoon regardless of how well the converter is set, that’s less about height and more about standing too long without sitting back down, exactly the pattern NIOSH’s research flagged.
Frequently Asked Questions
How do I know my desk converter is set too high?
Your shoulders will shrug up toward your ears and your wrists will bend backward when you type. Lower the keyboard tier until your forearms sit roughly parallel to the floor.
Can I use a desk converter on any desk?
Mostly, but check the converter’s footprint against your desk’s depth first. A converter deeper than your desk surface will overhang the edge and feel unstable.
How long should I stand at a time?
There’s no single verified number for everyone, but NIOSH’s research on prolonged standing supports switching positions regularly rather than standing for hours straight. Start with shorter stretches and extend them as it feels comfortable.
Do I need a separate keyboard tray with a converter?
No, most converters include a built-in keyboard tier that serves the same purpose. A separate tray is only useful if the converter’s tier can’t reach your correct height.
Is a two-tier or single-tier converter better for ergonomics?
Two-tier is usually better, since it lets you set keyboard and monitor height independently. A single-tier platform forces a compromise between the two.
What’s the biggest mistake people make setting up a desk converter?
Measuring the converter’s height range instead of their own elbow height. The converter’s specs tell you what’s possible, not what’s correct for your body.
Get your converter’s keyboard tier within 1 to 2 inches of your standing elbow height, confirm the monitor tier separately, and check both again seated. That’s most of the setup. The rest is remembering to actually sit back down instead of standing through the whole day.
