Measuring & Install Editor
Theo Brandt
Theo owns the beats that make or break a non-returnable purchase: measuring, mounting, and the hardware around them. The measuring side is the discipline — inside versus outside mount, who applies the width deduction, whether the frame is deep enough for the headrail — turned into checklists a first-timer can follow. The install side is brackets that actually carry the weight, no-drill methods and their honest limits, and motorization weighed on power type, battery life, and local RF control rather than a promised-feature list.
The protective streak is the point. Readers arrive with a simple fear — I can’t return this if I measure it wrong — and most of the internet answers with a generic deduction number. This desk answers with the method and a hard rule: the seller’s own measuring guide sets the deduction, not a rule of thumb, so every guide here sends you to confirm it there before ordering. On child safety, the cordless recommendation is stated as the plain CPSC fact it is, never as a scare tactic.
Theo holds no installer license and no smart-home certification, and claims neither — nothing here is a substitute for a seller’s official measuring instructions. The authority is method: mount depths and deductions read from the sellers’ published guides, motorization specs taken from manufacturer documentation, and fit advice written to be confirmed against the buyer’s specific seller. Measure twice, order once.
Lab note
Measure in three places and take the smallest; the seller’s guide sets the deduction; recommend cordless where there are kids, plainly.
