About yangmk
yangmk is a one-person site, built by an engineer who got tired of re-deriving the same setup numbers every time he moved a desk.
Show the math
Everything here follows one rule: if a guide tells you what to do, it also has to show where the number came from. “Put your monitor at eye level” is not useful on its own — you want to know what that means in centimetres for your height, and what to do when your desk cannot go that low. Same for the tools: the desk height calculator gives you a number and the formula behind it, so you can sanity-check it against your own body instead of trusting a blank input box. The whole model — every ratio, the population data it was checked against, and the mistakes published along the way — sits on the methodology page.
What this site is not
It is not a review farm and it is not written to rank. Pages get published when there is something concrete to measure or calculate, and they get corrected when the numbers turn out to be wrong. Some pages carry affiliate links; they never change what gets recommended, and they are disclosed on every page that has them.
Get in touch
Corrections are genuinely welcome. If a number is off, or a recommendation does not match what you measured at your own desk, email hello@yangmk.com — say what you measured and I will fix or qualify the page.
