The short answer
Above roughly 6'2", the Ergotron WorkFit-S is the only converter we would recommend without qualification — it publishes 18" of tandem travel plus 5" of independent monitor adjustment, and it clamps to the desk edge rather than standing on the surface. The alternative fix is to raise your existing desk on risers and then use any converter you like.
The arithmetic
A converter's published lift is measured from your desk surface. So the height you actually get is your desk height plus that figure, and a standard desk is about 29".
|
| 6'0" | about 43" – 44" | 46.5" — ample | 48.7" — ample | about 47" — ample |
| 6'2" | about 44" – 46" | 46.5" — just enough | 48.7" — ample | about 47" — ample |
| 6'4" | about 46" – 47.5" | 46.5" — short | 48.7" — enough | about 47" plus 5" monitor lift |
| 6'6" | about 47.5" – 49" | short | 48.7" — marginal | enough, monitor set independently |
Note how quickly the margin disappears. At 6'4" the Pro Plus 36 — the best converter on this site by every other measure — is already short, and no accessory fixes it.
Why the arm wins
The WorkFit-S is not a better platform. It is a different machine. Ergotron publishes that the monitor and keyboard adjust 18" in tandem, with the monitor adjusting a further 5" independently, for a maximum monitor height adjustment of 23".
That independence is the point, and it matters most for tall people:
- Your elbows set the keyboard. Roughly 46" to 49" for a tall user.
- Your eyes set the monitor. The top of the screen should sit near eye level, which for a 6'5" user is around 62" to 64" from the floor.
On a platform those two are welded together, so a tall user ends up with a screen far below eye level and their neck angled down all day. On an arm they are set separately. That is why we rank the WorkFit-S first here and second in the general roundup.
The trade is the load limit: Ergotron publishes a maximum total load of 24 lb on the height-adjustment assembly for the single-monitor LD model and 25 lb for the dual. One large monitor and a laptop is already close. Check your monitor's published weight before ordering.
The other fix: raise the desk
If you like a platform converter and it is two inches short, raise the desk underneath it. Desk risers, furniture blocks or a set of four adjustable feet will lift a standard desk by two to five inches, and that moves the whole range up with it.
Check this before you do it
Raising the desk raises your seated height too. If you now cannot sit at it comfortably, you have traded one problem for another — raise your chair and add a footrest, or accept that a
full sit-stand desk is the cleaner answer.
How we picked
Every pick earns its place on the numbers
Each product here is chosen the way a well-informed buyer would choose it: read the maker's spec sheet, manual and warranty terms; record the figures that decide whether a desk fits a body and stays still at height; confirm replacement parts are actually sold; then score it against a published rubric. The UPLIFT V2 adds something extra — it is owner-tested long-term, the desk Mike bought and works at daily.
Scores are weighted editorial judgments from that documented research, shown as a criterion-by-criterion breakdown so you can see which strengths earned each ranking. Nobody pays for placement. The rubric and the weights are on the How We Pick page.
