Getting a custom order wrong costs time and money. A door that arrives even a quarter-inch too wide means re-ordering, waiting weeks, and reopening a project you thought was finished.
For anyone ordering custom aluminum profiles, precision at the measurement stage is what separates a smooth installation from a frustrating one. These six dimensions are what suppliers need before they cut a single piece.
Here are the six measurements every custom aluminum cabinet door profile order requires.
Overall Door Width
The first thing any manufacturer needs is the finished door width. Because aluminum cabinet door frames are cut to your exact specification, the number you submit directly determines what shows up.
Measure the opening width at three points – the top, the middle, and the bottom – then use the smallest reading. Cabinet openings aren’t always perfectly square, and using the largest measurement creates a door that won’t close.
Before you submit, subtract any required clearance gap (typically 1/16 inch to 1/8 inch per side). That small deduction is easy to forget, and it causes a door that binds against the frame the moment temperatures shift.
Write the finished door width – not the raw opening dimension – and mark it clearly on your order form so there’s no ambiguity between the two. Aluminum cabinet door frames are engineered with tolerances that accommodate standard clearance reductions, so you don’t need to manually adjust raw opening measurements on top of that.
Overall Door Height
Door height follows the same logic as width. Measure from the top of the opening to the floor of the cabinet at three points – left side, center, and right side – and use the smallest reading. Apply a clearance deduction of 1/16 inch to 1/8 inch at top and bottom.
Tall cabinet openings tend to vary more than short ones, so those three measurement points really matter here. Don’t assume a 36-inch cabinet produces a 36-inch door; the actual interior dimension is almost always a little different once you factor in face frame thickness or cabinet box construction. Submit the exact finished height you need.
And if you’re ordering pairs of doors for a single opening, confirm whether both doors share the same height or differ slightly due to an unlevel floor; manufacturers cut to your number, so that distinction has to be clear before the order goes into production.
Frame Profile Width
Profile width refers to the visible face of the aluminum rail that borders the door – the part your eye lands on when the cabinet is closed. Most aluminum door profiles come in standard widths ranging from 3/4 inch to 2 inches, but custom orders let you specify exactly what you need.
This measurement matters for visual consistency across a run of cabinets; it also affects how much panel area you actually get.
A wider frame eats into the glass or wood insert space, while a narrower one maximizes the panel but thins out the structural border. Know the look you want before you order. Sleek contemporary doors favor a 3/4-inch to 1-inch profile, while transitional styles often use a 1.5-inch rail for more visual weight.
Specify the exact width in decimal inches or millimeters – whichever format your supplier requires, and confirm whether that dimension is the face width or the full profile depth.
Panel Thickness
The panel – whether glass, wood, or acrylic – needs to fit the profile’s groove without slop or force.
Manufacturers need to know the exact panel thickness so the groove they mill accepts the material cleanly. For tempered glass, the most common insert in aluminum cabinet doors, standard thicknesses run from 1/4 inch to 3/8 inch.
Wood panels and MDF tend to run from 1/4 inch to 1/2 inch. But here’s the thing: don’t guess the thickness. Use a caliper on the actual sheet you plan to install, because glass and wood both carry real-world tolerances that can differ from the nominal size on the label.
A 1/4-inch glass lite might actually measure 0.218 inches, and a groove milled for exactly 0.250 will grip it too loosely. Give your supplier the measured thickness and ask whether they build any tolerance into the groove or cut it to the exact number you provide.
Reveal and Overlap Dimensions
Reveal is the gap between adjacent doors or between a door and the cabinet face frame; overlap is how far the door sits over the cabinet box opening. Both affect how the finished installation looks and how the doors actually function.
An overlay door needs an exact overlap dimension so it covers the cabinet box edge without hitting an adjacent door or a perpendicular cabinet run. An inset door needs a precise reveal – typically 1/16 inch to 3/16 inch on each side – so it sits flush without binding.
Submit both numbers even if you think one is a standard, because manufacturers working across many clients can’t assume your project follows any single convention.
If your cabinet layout includes doors sharing a center stile, measure from the stile face to each door edge and note whether the reveal applies to one door or splits equally between the pair.
Hinge Placement and Clearance
Hinge type and placement tell the fabricator where to stop the profile or bore for hardware – and they also affect which profile system you can order.
A full overlay door on a concealed European hinge has different clearance needs than a face-frame door on a traditional surface mount. So specify the hinge type, the number of hinges per door, and the distance from each hinge centerline to the top and bottom of the door.
For aluminum profile doors, some hinge systems attach directly to the profile while others require a backing plate or a specific bore pattern. If you plan to use a hinge with a 110-degree or 165-degree opening angle, confirm that the profile corner joint allows for the swing without the door fouling the cabinet side panel.
Get that number wrong and the door stops short of fully open – which defeats the entire purpose of a wide-swing hinge.
Conclusion
Accurate measurements turn a custom order into a finished installation that fits right the first time. Width, height, profile width, panel thickness, reveal and overlap, and hinge clearance are the six numbers every supplier needs before production starts.
Take each measurement at multiple points, account for clearance gaps, and submit your actual measured dimensions rather than nominal sizes. That discipline at the start saves re-cuts, delays, and real cost later in the project.
