External Depth refers to the measurement from the front face of a coffee bar cabinet to its rear surface. The correct depth depends on the specific dimensions of your espresso machine and the amount of clearance required to operate it comfortably.
Which External Depth suits your coffee setup?
| If this is you | The External Depth that suits you | Why |
|---|---|---|
| You own a compact pour-over setup or a small capsule machine. | 12 in. to 15 in. | These machines have a small footprint and do not require significant clearance for operation. |
| You use a standard home espresso machine with a portafilter. | 18 in. to 21 in. | This provides enough room for the machine body plus the space needed to lock in and remove the portafilter handle. |
| You own a large-format semi-automatic machine or a multi-group unit. | 22 in. to 24 in. | Larger machines require extra depth to ensure the front of the unit does not protrude into walking paths. |
| You need to store large storage bins or bulk coffee beans alongside your machine. | 24 in. or greater | Extra depth allows for deep shelving that can accommodate bulky items without crowding the primary workspace. |

How do I measure the correct External Depth for my coffee bar cabinet?
To determine the correct External Depth, you must measure your primary coffee equipment and add a functional buffer. Start by measuring the depth of your espresso machine from the front of the base to the rear of the housing. If your machine has a protruding portafilter handle or a steam wand that swings outward, include that distance in your measurement.
Adding the operational clearance buffer
A common mistake is ordering a cabinet that matches the exact depth of the machine. You must add at least 2 in. to 3 in. of “swing space” to the machine’s depth. This ensures you can move your hands, clear away used grounds, or reach the water reservoir without hitting the cabinet’s front edge or the wall behind it.
Where to find the depth on your equipment
If you do not have the machine in front of you, locate the manufacturer’s technical specifications online. Look for the “Depth” or “Footprint” measurement. Note that some manufacturers list the depth of the base only, excluding the handle; always account for the handle’s protrusion when calculating your cabinet needs.
What happens if the External Depth is too shallow?
If the External Depth is too shallow, the machine will likely overhang the front edge of the cabinet. This creates a physical hazard as the front of the machine becomes a protruding corner in a high-traffic kitchen area. It can also lead to “clearance conflict” where the rear of the machine hits the wall, preventing the unit from sitting flush against the back of the cabinet.
Portafilter and steam wand interference
In a shallow cabinet, you may find it impossible to remove a portafilter because there is no room for your hand to grip the handle. Similarly, if the cabinet is too close to a wall, a pivoting steam wand may hit the back panel before it can reach a milk pitcher, limiting your ability to froth milk effectively.

What happens if the External Depth is too deep?
An External Depth that is too large may occupy valuable floor space or block walkways in a narrow kitchen. If the cabinet is significantly deeper than your equipment, you may end up with “dead space” at the back of the unit that is difficult to reach or organize.
Impact on kitchen flow
A cabinet with a 24 in. External Depth takes up considerably more floor real estate than a 15 in. unit. In small apartments, this extra 9 inches can be the difference between a clear walkway and a cramped passage. Always measure your available floor area to ensure the cabinet does not protrude into a doorway or a primary cooking zone.
What should I do if I fall between two External Depth sizes?
If your measurements place you between two standard sizes, such as needing 20 in. when only 18 in. and 24 in. are available, you should prioritize the larger depth. It is much easier to utilize extra space inside a deep cabinet than it is to manage a machine that hangs over the edge of a shallow one.
Why the larger depth is the safer choice
Choosing the larger depth ensures that you have the necessary clearance for the machine’s operation and any future accessories you might add. If you choose the smaller size and find it is too tight, the only solution is to move the entire cabinet further into the room, which may not be possible. The larger depth provides a safety margin for the “swing” of the steam wand and the grip of the portafilter.
Checking the return policy for sizing errors
Because External Depth is a physical dimension that cannot be altered once the cabinet is built, verify the return policy before purchasing. If you are unsure about the final measurement, look for a supplier that offers a clear return or exchange process for items that do not fit the intended space.
