What Is a Double Front Door?
A double front door is a two-panel entry system where both doors are operable, meeting at the center with an astragal (a vertical strip that seals the gap between the panels). Unlike a single door with sidelights, a true double door gives you a full-width opening when both panels swing open.
The standard width for a double front door ranges from 60 to 72 inches, with heights typically at 80 inches (6’8″) or 96 inches (8’0″). The most common configuration is 60 x 80 inches—two 30-inch door slabs side by side. This is the size you will find stocked by most manufacturers and distributors.
Standard Double Door Dimensions: A Complete Guide
When specifying double doors, you need to distinguish between three measurements:
- Door slab dimensions — the actual size of each door panel
- Rough opening — the framed opening in the wall, which is larger than the door unit
- Frame size — the overall width including the jambs
For a 60 x 80 double door, the rough opening should typically be 62 to 63 inches wide and 82 to 83 inches tall. This extra space accommodates the frame, shims, and leveling adjustments. The door slabs themselves are each 30 inches wide, and the frame adds roughly 2 to 3 inches to the total width.
Most residential double doors use the same height standard as single entry doors: 80 inches. If you are working on a project with taller ceilings or custom architecture, 96-inch doors are available but typically require a custom order.
Double Door Size Chart
| Configuration | Each Slab Width | Total Door Width | Common Height | Rough Opening Width |
|---|---|---|---|---|
| 60″ x 80″ | 30″ | 60″ | 80″ | 62″–63″ |
| 64″ x 80″ | 32″ | 64″ | 80″ | 66″–67″ |
| 68″ x 80″ | 34″ | 68″ | 80″ | 70″–71″ |
| 72″ x 80″ | 36″ | 72″ | 80″ | 74″–75″ |
| 60″ x 96″ | 30″ | 60″ | 96″ | 62″–63″ |
| 72″ x 96″ | 36″ | 72″ | 96″ | 74″–75″ |
The 60 x 80 size is the industry standard for residential double front doors. The 72-inch width is common for high-end homes and commercial applications where wider passage is desired. If you need a door wider than 72 inches, you are moving into custom territory.
How to Measure for Double Front Doors
Before ordering, verify your rough opening dimensions. Here is the measurement process:
Width: Measure the opening at three points—top, middle, and bottom. Use the narrowest measurement for your rough opening width.
Height: Measure from the finished floor to the top of the rough opening at both the left and right sides. Use the smaller number.
Depth: Measure the wall thickness from the interior drywall to the exterior sheathing. Standard residential walls are typically 4-9/16 inches or 6-9/16 inches deep.
Check for square: Measure diagonally from corner to corner in both directions. If the difference exceeds 1/4 inch, the opening is out of square and needs correction before installation.
For a replacement door, measure the existing frame’s exterior dimensions and compare them against the new unit’s frame size. A common mistake is ordering a door slab when you actually need a pre-hung unit, or vice versa.
Exterior Double Doors with Glass: Size and Style Options
Glass adds complexity to double door dimensions because the glazing affects the door’s weight and structural requirements. Standard sizes still apply, but the glass panel configuration influences how the door is engineered.
Common glass configurations for exterior double doors include:
- Full-lite — one large glass panel occupying most of the door, typically with a 4- to 6-inch bottom rail
- Half-lite — glass in the upper half, solid panel below
- 9-lite or 15-lite — multiple smaller glass panes separated by muntins or grilles
- Sidelight-style — narrow glass panels integrated into the door stiles
For a 60 x 80 double door with full-lite glass, each glass panel is typically around 24 to 26 inches wide and 68 to 70 inches tall. The actual glass size depends on the door’s stile and rail widths, which vary by manufacturer.
Glass adds significant weight. A 60 x 80 double door with two full-lite panels can weigh 100 to 150 pounds per slab, depending on whether you choose single-pane, double-pane, or triple-pane glazing. This affects hinge requirements—most double doors with glass need three hinges per slab, and heavier configurations may require ball-bearing hinges or continuous hinges.
If you want glass but are concerned about security or energy performance, consider tempered or laminated glass. Building codes in most jurisdictions require tempered glass in doors and adjacent sidelights.
Building Code Considerations
Double front doors must meet egress and accessibility requirements. The International Residential Code (IRC) requires at least one egress door with a minimum clear opening of 32 inches wide and 80 inches tall. This means at least one of your double door panels must open to at least 32 inches of clear width when measured from the open door face to the door stop.
For a 60-inch double door with two 30-inch slabs, each slab provides roughly 29 to 30 inches of clear opening once you account for the door stop and hardware. This may not meet the 32-inch requirement. A 64-inch or 72-inch double door gives you more flexibility, since each slab is wider.
Check your local code before specifying. Some jurisdictions adopt the International Building Code (IBC) for multi-family and commercial projects, which has different requirements than the IRC for single-family homes.
Common Questions About Double Door Dimensions
Can double front doors be custom-sized?
Yes. Most manufacturers offer custom sizing, but expect longer lead times and higher costs. Custom sizes typically require a minimum order and may not be returnable. If your rough opening is non-standard, verify the exact dimensions with the manufacturer before ordering.
Are 60 x 80 exterior double doors a standard size?
Yes, this is the most common standard size. It is widely stocked and typically the most affordable option because it uses standard door slabs and frames.
What is the rough opening size for a double door?
For a 60-inch door, the rough opening should be 62 to 63 inches wide. For a 72-inch door, plan on 74 to 75 inches. The height should be 82 to 83 inches for an 80-inch door. These dimensions account for the frame, shims, and leveling.
Can I use a double door in a standard single-door opening?
No. A double door requires a wider rough opening. Widening an existing opening is a structural change that involves framing modifications and possibly a new header. This is typically a significant construction project, not a simple swap.
Related Considerations for Double Front Doors
Materials and weight. The door material affects both dimensions and hardware requirements. Aluminum double doors with thermal break profiles are common for commercial and modern residential applications because they are lighter than solid wood while offering structural rigidity. Solid wood doors, such as oak or mahogany, are heavier and require stronger hinges and frames. When comparing materials, consider the door’s weight per slab and whether your framing can support it.
Hardware for double doors. Double doors require specialized hardware that single doors do not. The active door (the one used most often) needs a lockset, while the inactive door uses flush bolts at the top and bottom to secure it to the frame and threshold. An astragal seals the gap between the two doors. Multipoint locking systems are recommended for exterior double doors because they secure the door at multiple points along the height, reducing warping and improving security.
Threshold and weather sealing. The center meeting point of a double door is a potential weak spot for air and water infiltration. Look for doors with an adjustable astragal and a threshold with a compression seal. This matters more for double doors than single doors because the center seam is unique to this configuration.
Egress and furniture movement. Double doors are often chosen for their wide opening, which simplifies moving large furniture in and out. If this is a primary reason for your choice, verify that both doors open fully and that the clear opening width meets your needs.
Customization and sourcing. When you need double doors in non-standard sizes or with specific glass configurations, working directly with a manufacturer gives you more control over the specifications. As a factory-based manufacturer, we handle the full range of customization: door dimensions, glass type, hardware finish, and color. Our approach is straightforward—you provide your rough opening dimensions and performance requirements, and we engineer the door unit to match. This is particularly useful for projects with unusual sizes or when you need the door to meet specific local building codes.
For B2B buyers sourcing double doors in volume, the key is to confirm the manufacturer can provide the exact sizes you need, offer pre-shipment quality inspection, and handle the documentation required for international shipping. We supply both FCL and LCL shipments directly from our factory, with adjustable profile structures to match the building codes of your target market.
