Measure first: a short guide to fit before ordering
The five numbers worth writing down before you buy any small household aid — and how to read a listing that leaves them out.
In short
Answer: Write down the clear internal dimensions, the surface, the fixing method, the projection and the empty weight. If a listing gives none of them, treat that as information rather than a reason to guess.
Key facts at a glance
- Measure the clear internal size, not the outer face of the furniture or appliance.
- A listing without dimensions is incomplete; it is not evidence that a product is universal.
- This page is a general measuring primer and makes no product-specific claims.
What this section covers
Most disappointing purchases are not bad products. They are the right product in the wrong size. The same pattern repeats: the divider is wider than the drawer, the sleeve does not fit a D-shaped shaft, the tray is heavier empty than expected, or the paddle hits the sink edge before it presses the pump.
Five numbers cover nearly all of it: the clear internal width and depth where the item will sit; the surface it will attach to (smooth tile, painted wood, laminate, fabric); the fixing method and any hole centres; how far the item projects once fitted; and its weight empty. Write them on one piece of paper and keep it next to the computer while you compare listings.
Then read the listing as a checklist, not as an advertisement. Marketing words describe a feeling; measurements describe a fit. If one of the five is missing, a search image rarely settles it — the sensible move is to check the maker's detail page or choose a product that publishes the number.

Read the guideQuestions people actually ask
What is 'clear internal width'?
The unobstructed space inside the drawer or opening, measured between the side walls, not across the furniture front.
Why does surface matter?
Adhesive pads and suction cups need smooth, clean, non-porous surfaces; grout lines and texture break the seal.
Should I measure in centimetres or inches?
Use the unit the listing uses, and convert once — a conversion error is a common cause of a bad fit.
What if my measurements fall between two sizes?
Choose the smaller item with an adjustable range, or ask the seller for the exact tolerance.
