Standard commercial bar dimensions are a 42 inch front bar height, a 30 to 36 inch back bar counter, a working aisle of 36 to 42 inches between them, and a bartender station height of 38.78 inches. Equipment cutouts and clearances are what actually decide the layout.
Most bar dimension guides give a single number and move on. The numbers below are the ones that change what you can build: what the equipment needs, what a body needs to move, and where those two disagree.
Standard bar heights
Bar height is the first decision and the hardest to change later. The front bar, where guests stand, sits at 42 inches. The bartender works at a lower surface so the guest cannot see the well, which puts the station top at 38.78 inches. A back bar counter runs 30 to 36 inches, low enough to work from without stooping.
Front bar, guest side
42 inches / 1,067 mm
Bartender working surface
38.78 inches / 985 mm
Back bar counter
30 to 36 inches / 762 to 914 mm
Recommended bar wall height for a drop-in station
45.28 inches / 1,150 mm
Foot rail
7 to 9 inches / 178 to 229 mm off the floor
Depths and widths
Depth is set by the equipment, not by taste. A commercial station is 23.62 inches deep, so a bar top covering it needs at least 24 inches plus whatever overhang you want on the guest side. The aisle behind is what most plans get wrong: 36 inches works for one bartender, 42 inches is the minimum where two people pass each other during service.
Station depth
23.62 inches / 600 mm
Bar top depth over a station
24 inches minimum, 26 to 30 inches with overhang
Working aisle, single bartender
36 inches / 914 mm
Working aisle, two or more
42 inches / 1,067 mm
Bar wall depth for plumbing and electrical
5.91 inches / 150 mm minimum
Equipment cutouts and clearances
A drop-in station needs a cutout smaller than the unit, because a 1 inch lip carries the weight on the counter. Get this wrong and the station either falls through or will not seat. The retractable faucet is the clearance people forget: it adds 7.09 inches above the station, which is exactly where an overhanging bar top tends to be.
52 inch drop-in cutout
50.59 x 22.83 inches / 1,285 x 580 mm
65 inch drop-in cutout
65.20 x 23.82 inches / 1,656 x 605 mm
Edge lip resting on the counter
1 inch / 25.4 mm
Clearance around the unit
3 to 5 mm on all sides
Retractable faucet adds
7.09 inches / 180 mm above the station
Ice wells, speed rails and drink rails
The components have their own dimensions, and they drive capacity rather than fit. A 135L ice well holds roughly 200 cocktails worth of ice through a shift, a 168L well roughly 300. Speed rail length decides how many bottles sit at fingertip reach, which is the single biggest influence on how many steps a drink takes.

65 and 88 inch ice chest

Drink rail
4.7 inches deep, 0.78 inches tall / 119 x 20 mm
Plumbing and drainage
Drainage decides where the bar can physically go. Every ice well, rinse unit and drip rail on a commercial station drains through a 2 inch line, and that line needs fall. A quarter inch per foot is the working number, which over a long bar adds up to real height you have to plan for under the counter.

Frequently asked questions
The front bar, on the guest side, is 42 inches. The bartender works lower, at 38.78 inches, so the well and the mess stay out of sight. A back bar counter runs 30 to 36 inches.
A commercial station is 23.62 inches deep, so the bar top over it needs at least 24 inches, and 26 to 30 inches once you add a guest-side overhang.
Thirty-six inches of working aisle is enough for one bartender. Where two or more people work the same run, 42 inches is the minimum before they start colliding during service.
Smaller than the station, because a 1 inch lip carries the weight on the counter. A 52 inch drop-in needs 50.59 x 22.83 inches and a 65 inch needs 65.20 x 23.82 inches, on a base of at least 3/4 inch exterior-grade plywood.
The retractable faucet adds 7.09 inches above the station, so a drop-in reaches 22.83 inches and a standalone 45.87 inches when raised. Check it against any overhanging bar top before you cut.
