The one number that decides a converter
A converter's published lift is measured from the top of your existing desk, not from the floor. That single fact is responsible for most of the disappointment in this category, because it means the height you actually get is your desk height plus the converter's maximum — and a standard desk is about 29 inches.
Run it. A VariDesk Pro Plus 36 publishes 17.5" of lift, so on a 29" desk your standing keyboard height is about 46.5". If your measured standing elbow height is 48", that converter cannot work for you at any price and no accessory changes it. A VIVO 36in or 32in Converter publishes about 17", which gets you to about 48.7". An Ergotron WorkFit-S publishes 18" of tandem travel with a further 5" of independent monitor adjustment, and because it clamps to the edge rather than standing on the surface, it behaves differently from all of them.
The arithmetic is the whole answer: the desk height plus the converter's maximum lift is your standing keyboard height, and nothing else about the converter can change it. Tying the fit claim to the desk it sits on is the correct way to state a converter's reach, and almost nobody in the category does it.
Weight limits are far tighter than you expect
Full sit-stand desks are rated for 200 to 440 lb. Converters are rated for 24 to 44 lb. That is not a misprint, and it is the second most common reason a converter disappoints. Two 27-inch monitors with their factory stands commonly total 24 to 36 lb together — already at or past the limit of every platform we rank, before you add a keyboard.
So the check is concrete: look up your monitors' published weights, add them, and compare. Ergotron publishes 24 lb maximum total load on the height-adjustment assembly for the single-monitor WorkFit-S LD and 25 lb for the dual; VIVO publishes 33 lb for both its 32in and 36in risers; Vari publishes 44 lb for the electric Pro Plus. Those are the numbers that matter, and they are all on the makers' own pages.
Platform or clamp-on arm
These are two different products sharing a category name. A platform sits on your desk and lifts a slab carrying your whole setup — simple, stable, and it permanently occupies its own footprint whether you are sitting or standing. Vari recommends a 25.75" deep desk with clearance for the Pro Plus 36 to reach full height, and plenty of home desks are 24".
A clamp-on arm costs you no desk surface at all and lets the monitor move independently of the keyboard — which matters because your elbows set one height and your eyes set the other. On a platform those two are welded together, so a setup that is right for your arms usually puts the screen too low. For tall users that is decisive.
When a converter is the wrong purchase
If you are under about 5'4". A converter raises a surface that is already too high for you, and it never drops flush — the VIVO 32in bottoms out at 6.5" above your desk, permanently. Short users need a desk that goes lower, and only a full frame does that. The full comparison covers the other three situations where a full desk is the better buy.
