How wide should a round outdoor dining table be on a city sidewalk?

Corners catch things on a sidewalk. A hip, a stroller wheel, the strap of a bag swinging past the rail. A round top gives the walkway nothing to snag, and every guest at it sits the same reach from the middle.

That is the case for the round outdoor dining table on a city front. The case against it is just as plain: rounds do not push together, and the big ones eat depth you may not have between the facade and the clear walkway. So the work is picking the diameter, putting the right foot under it, and testing it against your strip before the order goes in.

Four sizes do most of the work

Our outdoor rounds run from 24 inches across up to 48. Two-tops sit at 24 and 30 inches, coffee on the small one and a full lunch on the larger. A 36 seats four in close quarters. At 42 and 48 inches a round takes four to six, and the 48 sits five or six without anyone tucking an elbow.

Want to check a size yourself? Take the distance around the top and divide it by about 24 inches, one guest per stretch. A 36-inch round measures about 113 inches around, which is four guests with a little left over. A 42 comes to about 132 inches, so five. A 48 runs about 151, so six.

Here is the plain limit. Past 48 inches the outdoor list holds a single round, a quartz top at 54 inches, and there is no 60-inch round at all, which is the planning size for a party of eight. Seat eight outside on two tables or one long rectangle.

No corners in the walkway

A 36-inch square and a 36-inch round seat the same four. Turn them on the concrete, though, and they act differently. The square measures nearly 51 inches corner to corner, so a table knocked off line by a guest swings a point out toward the people walking by. The round stays 36 inches whichever way it turns.

On a quiet street that is cosmetic.

On a busy one, it is the gap between a clear path and a server stepping around a corner with four plates, a dog leash crossing her shins and the evening crowd stacking up behind. Staff cannot square every table after every party. A circle never needs squaring.

Measure the strip, chairs and all

A table on paper is a top. On the sidewalk it is a top with chairs around it, and the chairs are where the depth goes.

Take an 8-foot seating strip, 96 inches from the facade to the edge of the walkway, and an outdoor ladder-back chair that is 18 3/4 inches deep with an 18-inch seat. Set a 36-inch round with one chair against the building and one facing it from the street side. Chair, top and chair add up to 73 1/2 inches, and 96 minus 73 1/2 leaves 22 1/2. A guest standing up pushes the chair back 18 to 24 inches, so the one by the wall rises without a shuffle.

Swap in a 42-inch round on the same spot. Top and chairs now reach 79 1/2 inches and leave 16 1/2. The wall-side guest is pinned.

Along the front the arithmetic runs the same way. Say the strip is 40 feet long, 480 inches. Four 36-inch rounds with their chairs take 294 inches. Leave about 36 inches between neighboring chair backs for a server, three gaps or 108 inches, and the row comes to 402 inches with 78 to spare. A fifth table would need 511 1/2. Four rounds, sixteen seats.

Measure chair depth from the record, not from memory: the patio chairs list the inches for each model. And before any of this, confirm with your local rules how wide the walkway must stay clear. Plan the seats in what is left over, never the other way around.

Put a wide enough foot under it

Outside, a round top rides on a single base, and the spread of that base decides how it answers a hard lean on the edge. Rule of thumb: the foot spans at least two thirds of the top. Under a 36 that is 24 inches. Under a 42, 28 inches. Under a 48, 32.

Our stainless steel round outdoor table base comes with a 17, 22 or 28-inch foot and stands 28 3/4 inches tall. The black round steel table and umbrella base is listed for patio use with a 17, 22 or 30-inch foot at 28 inches. Under a 42, the 28 just meets the mark and the 30 clears it by two.

Now the mistake. A buyer sizes up to a 48 for a roomier four and orders the widest round foot on the page. Two thirds of 48 is 32 inches, and neither base reaches it, since the 30-inch foot falls two inches short. Choose a 48 that ships with its own base, like the teak outdoor restaurant table, listed with a 48-inch round top on a wood base, 30 inches high and 39 pounds. The outdoor table base guide goes further into spread and height.

Then add the top to the base. A half-inch top on the 28 3/4-inch stainless base finishes at 29 1/4 inches. Dining height is 29 to 30, so that lands in range. Over that 18-inch seat it leaves 11 1/4 inches to the tabletop, right between 10 and 12.

Shade through the middle

A round top puts the umbrella pole in the one spot everyone shares. Plan the hole when you order, not with a drill in June.

This resin tabletop in heritage oakwood with a phenolic edge is half an inch thick, comes in 36, 42 and 48-inch rounds as well as two-top sizes, and lets you pick an umbrella hole on the order page. The tempered glass patio table has its hole already cut and stands 30 inches on a steel base, in 24 and 32-inch rounds. Browse the patio tables with an umbrella hole for more, and choose the canopy itself from the patio umbrellas. Close it when the gusts come down the block.

Surfaces vary. Round tops on our outdoor list come in resin, tempered glass, teak, black steel and quartz, and the whole range sits in the patio tables. Each wants a rinse after the last seating and a cover or a dry corner at season end. Patio tables carry a six-month warranty, and that cover expects the table to have been looked after.

A cardboard circle on the pavement

Cut a circle of cardboard at the diameter you chose, 36 inches is a yard across, and lay it on the real spot at your busiest hour. Set two of your chairs beside it and watch the walkway for ten minutes. If strollers swing wide around it, drop a size.

Then write the round into an outdoor plan: diameter, top finish, base and foot size, finished height, and whether it takes a pole. Fours on square tops are compared in the outdoor dining set 4 guide, and two-tops built from parts have their own outdoor bistro table guide. Still unsure which foot fits a 48?
