They all promise to save space. Their actual footprints tell a different story. We gathered dimensions from the brands themselves so you can compare—not guess.
ENTER YOUR SPACE TO FIND MATCHES ↗How we chose these: a range of fixed, narrow, expandable, and foldaway designs with published measurements from the brand. The numbers below are manufacturer-stated dimensions, not our firsthand measurements. These are not ranked “best” products. Maker links are ordinary source links—not affiliate or paid links.
Simple, low-profile countertop option for a small number of plates and utensils. It takes less of your worktop than many full-size metal frames.
The maker provides these three dimensions without axis labels. For our calculator, we provisionally treat them as width × depth × height; confirm orientation against the product illustration before ordering. Corners are intended for pouring off collected water.
Only 9 inches wide when oriented as the maker specifies, with a tray that expands in depth for extra dishes. Useful if your available counter is narrow but deep enough.
Expansion increases depth considerably, so a fit while closed does not guarantee room for the fully extended tray or for its drainage path.
TEST EXPANDED SIZE ↗A larger drying area with a fold-down rack and cup holders, but a wide footprint. Better for spaces where the rack can sit out while drying and fold away for storage.
The open measurements are more relevant while dishes dry. The folded dimensions are mainly useful for storage, not for estimating capacity during use.
TEST FOLDED SIZE ↗A wider, expanding steel-frame design with adjustable drainage, better suited to people who need a flexible drying area than to the very smallest countertops.
The maker lists rounded inch equivalents of centimeter dimensions. Double-check sink access and where the movable drainage spout can empty.
TEST EXPANDED SIZE ↗A fixed frame with a swivel drain spout. The maker's diagram shows a smaller 12-inch inner extent as well as the 15-inch overall extent; use the full footprint for counter planning.
Source: maker dimension drawing for the brushed compact model, SKU KT1184DC, checked October 8, 2026. We map the diagram's horizontal span to calculator width and the full vertical top-view span to depth. Empty-frame height does not include your dishes. Confirm the spout path and exact current variant before ordering.
Very narrow countertop: check the Joseph Joseph Slim’s 9″ width, then confirm whether you have room for its depth and how its spout reaches the sink.
Straightforward tray drying: a basic OXO tray may make sense if it accommodates your actual dishes.
Want to store the rack away: the OXO Foldaway changes shape between use and storage, but its width stays substantial.
Wash more items regularly: a larger expandable model may be more useful if you have room to extend it.
Extend Slim versus Extend Steel: the Slim's stated closed width is 9 inches versus 14 inches for the Steel. Their closed depths are almost the same (12.2 versus 12.25 inches), while fully extended depths are 20.5 and 20.25 inches. A narrow width does not automatically mean a shallower rack. These are manufacturer inch values, with rounding; no capacity or drying-speed ranking is implied.
simplehuman on an 18 × 14-inch counter: its 15.5 × 15-inch full footprint fails the 14-inch depth in either flat orientation, even before a margin. The 12-inch internal span in the maker diagram is not a substitute for the overall size.
Missing evidence stays visible: OXO axis labels remain provisional. A separately researched Umbra Sinkin listing contains inconsistent dimensions, so that model is not included in the automatic matcher. None of these products has a loaded plate height measured by us.
