Which extending table fits your room, folded and fully open?
Enter the room size and the number of people. The calculator runs 51 real tables (23 from IKEA, 28 from Expand Furniture) through the chair clearances published by the National Kitchen & Bath Association and shows which ones still leave space to pull out a chair once the leaves are in.
How the seat count is worked out
NKBA Guideline 9 asks for a space 24 in wide and 18 in deep for each diner at a 30 in high table. The calculator uses the 24 in width only. Each long side holds the table length divided by 24, rounded down. Each end holds the table width divided by 24, rounded down, so a 35 in wide top seats one person per end and a 48 in top seats two.
Round tops are counted around the edge: a 43 in circle has an edge of about 135 in, which gives 5 places. Oval tops use the same idea with an ellipse formula.
Makers often print a bigger number. The Expand Furniture Junior Giant page says it seats up to 12 at 106 in; the 24 in rule gives 10 at that length (4 per side plus 1 per end). Both numbers appear on every result so the gap is visible.
Why the closed size gets its own line
A table that seats eight for a holiday spends most days at its small size. The closed footprint is what you walk around every day. Across the 51 tables, the closed top is on average 49% of the fully open area. The smallest closed top is the Expand Furniture Expanda v2 at 8.66 in deep.
Wall consoles and coffee-to-dining tables are not counted as seating while closed. A 17 in deep console is a shelf, and a coffee table at 11 in high is not a dining surface.
The four clearance choices
32 in, 36 in and 44 in come from NKBA Kitchen Planning Guideline 8; 60 in comes from the access standard printed beside it. The full wording, page links and how they were checked are on the clearance page. The figure is measured from the table edge to the wall or to the nearest thing that does not move.
What the table list covers, and what it leaves out
6 fold-down and flip-top tables, 10 wall consoles that pull out, 5 coffee tables that lift to dining height, and 30 pull-apart tables with leaves. Every size was read on Nov 5, 2026 from the maker's own product page. Prices are left out because they move week to week; each result links to the maker page where the current price sits.
Brands with sizes only in images or PDF drawings are not in the list yet. Outdoor tables and counter-height islands are left out.
What the math cannot see
Doors that swing into the room, radiators, window seats, floor vents and the swing of a fridge door all eat clearance. Leg position matters too: a gateleg with a center leg frame can block knees at one spot along the side. Chair size is not part of the check; a deep armchair needs more than a slim side chair. Treat a pass with less than 2 in spare as tight and measure again.
