Will It Fit Under My Sink?
Copy a product's width, depth and height from its spec table, add your cabinet numbers, and get a pass/fail on every constraint: door opening, clear zone width, usable depth, bend height, and the slide path if it is a drawer. Margins are shown so tight fits are visible before you buy.
Reading a product listing correctly
Use the overall or assembled dimensions from the specification table. Titles round down; photos lie by omission. For caddies, height includes the handle. For drawers, width means mounted width including rails, and depth means the closed length — the drawer also needs its full travel clear, which is what the slide-path check models.
Common questions
Where do I find a product's real dimensions?
In the listing's specification table, not the title. Use the assembled or overall dimensions; for caddies include the handle, for drawers use the mounted width.
What does the "turned sideways" note mean?
The box is wider than your door opening, but its depth is not, so it can enter rotated and turn inside. Fine for bins; risky for drawers that must mount square to the front.
Why did a product fail on the slide path?
You marked it as sliding, and its width exceeds your widest clear lane while the center is blocked. The rails would have to cross the plumbing band, which is a hard fail regardless of footprint.
The margin shows 0.3 in. Buy or not?
That is inside the 0.5 in margin this site recommends, so the verdict reads tight. Buy only if your measurements were careful and the product's spec is trustworthy; otherwise size down.
