Why Mobile Home Doors Are Different from Regular House Doors
The single biggest mistake mobile home owners make when replacing a door is assuming any standard house door will fit. Mobile home doors are built to different specifications — different rough opening sizes, different wall thicknesses, different frame depths, and different swing configurations than site-built homes.
Site-Built Home Doors
- Standard sizes: 32″ x 80″, 36″ x 80″
- Wall depth: typically 4½” to 6½”
- Exterior doors almost always swing inward
- Widely available at any hardware store
- Pre-hung units designed for 2×4 or 2×6 framing
Mobile Home Doors
- Common sizes: 32″ x 76″, 34″ x 76″, 36″ x 76″
- Wall depth: roughly 4″ to 6½” depending on age
- Exterior doors frequently swing outward
- Usually ordered from mobile home suppliers
- No universal standard — sizes vary by manufacturer and year
Do not buy a door before measuring. Mobile home door sizes are not consistent between manufacturers, models, or years. A door that fit a 1995 Fleetwood will not necessarily fit a 1995 Skyline. Always measure your specific rough opening before ordering — even if you are replacing with the exact same door brand.
A standard mobile home exterior door — the rough opening dimensions, swing direction, and frame depth all need to be measured before ordering a replacement.
Standard Mobile Home Door Sizes
Knowing the common sizes before you measure helps you understand what to look for. Mobile home doors generally come in 2-inch width steps. If your rough opening falls between standard sizes, you will likely need to order custom or reframe the opening.
| Door Size | Common Use | Era | Notes |
|---|---|---|---|
| 32″ x 76″ | Front and back exterior | 1980s–present | Very common exterior size |
| 34″ x 76″ | Front exterior, combo doors | 1990s–present | Common combo/storm door size |
| 36″ x 76″ | Wider front doors | 2000s–present | Newer and larger homes |
| 32″ x 72″ | Front and back exterior | Pre-1980 | Older homes — less common now |
| 28″ x 76″ | Interior bedroom/bathroom | Any era | Common interior size |
| 24″ x 76″ | Interior closet/utility | Any era | Narrower interior openings |
Older homes: If your home was built before 1980 there is a good chance the door height is 72 inches rather than the more common 76 inches. Measure the actual opening — do not assume the height based on the current door, as previous owners may have already replaced it.
How to Measure a Mobile Home Door — 6 Steps
Work through each step in order. Skipping any one of them is how you end up with a door that does not fit. All you need is a tape measure, a pencil, and your phone to photograph each measurement.
1Measure the Rough Opening
The rough opening is the actual hole in the wall — measured as if the door and frame were completely removed. This is the most important measurement of all six steps.
- Width: Measure horizontally from the inside face of one wall stud to the inside face of the opposite stud — not from trim to trim or frame to frame
- Height: Measure vertically from the top of the opening (bottom of header) to the floor
- Take three width measurements — top, middle, and bottom — and use the smallest
- Take three height measurements — left, center, right — and use the smallest
- Photograph each measurement with your phone before moving on
2Determine In-Swing or Out-Swing
This is where mobile homes differ most from regular houses. Most site-built exterior doors swing inward. Mobile home exterior doors frequently swing outward — and this affects where you take your measurements from.
- Out-swing door: Measure from inside the home — width wall to wall, height top to floor
- In-swing door: Measure from outside the home — width wall to wall, height top to floor
- Always measure from the opposite side to the direction the door swings
- Interior doors: same rule applies — measure from the opposite side of the swing
- If possible remove the old door first to get the cleanest measurement
3Left Hand or Right Hand?
Handing refers to which side the hinges are on — not which side the handle is on. Getting this wrong means the door opens the wrong direction.
- Stand on the outside of your mobile home facing the door
- If the hinges are on the left — you have a left-hand door
- If the hinges are on the right — you have a right-hand door
- Handing labels are not used the same way by every supplier, so when you order, also tell them which side the hinges are on and whether the door swings in or out
- Do not assume — check your own door before ordering
Stand outside and look at the door — if the hinges are on your left it is a left-hand door. If hinges are on your right it is a right-hand door.
4Measure the Frame Depth (Wall Thickness)
The frame depth — how deep the door opening is from inside wall surface to outside wall surface — determines what jamb width the new door needs. This measurement is often overlooked and causes fitment problems.
- Measure the depth of the door jamb from the inside wall surface to the outside wall surface
- Older mobile homes often have thinner walls, around 4 inches
- Newer mobile homes are often around 6 to 6½ inches
- The door slab itself is much thinner than the wall — what has to match the wall is the jamb (frame) width
- A jamb that is too narrow leaves a gap to fill with jamb extensions; one that is too wide sticks out past the wall and has to be trimmed
Measuring the frame depth — the distance from inside wall face to outside wall face determines the correct jamb width for your home.
5Standard or Non-Standard Size?
Compare your rough opening measurements against the standard sizes in the table above. Standard sizes are usually cheaper and easier to source than custom doors.
- If your opening matches a standard size — order standard, it will usually be faster and cheaper
- If your opening is between standard sizes — you have two options: order custom, or reframe the opening to the nearest standard size
- Reframing to a standard size is often cheaper than a custom door for a small difference
- Because sizes generally step in 2-inch widths, an opening that lands in between (say 33″) usually means reframing or a custom order — ask your supplier how they size their doors against the rough opening
- Always order based on the rough opening, not the old door size — the old door may have been the wrong size
6Storm Door or Combination Door?
If you want to add a storm door or replace a combination door, you need additional measurements beyond the basic rough opening.
- A storm door mounts on the outside of the exterior door frame — measure the full outside trim width and height
- Take a photo of the tape measure against the outside trim and bring it to the store
- Combination doors come as a door-and-storm unit on a shared frame — confirm your frame type and wall thickness with the supplier before ordering
- 34″ x 76″ is a common combination door size — but measure your specific opening first
- For storm door measurement: measure from outside edge of trim to outside edge of trim, both width and height
Where to Buy Mobile Home Doors
Mobile home doors are not always available at local hardware stores — big box retailers mostly stock house doors, not mobile home doors. Your best options are mobile home specialty suppliers and online retailers who ship directly.

Front Door, Back Door, Interior & Sliding Doors
Front Door
The most commonly replaced door on a mobile home. Front doors are typically constructed from steel, fiberglass, or wood and include security locks. The front door is the first thing visitors see — quality matters for both curb appeal and security. Use all 6 steps above and see the guide on exterior doors for mobile homes for material and style options.
Back Door
Back doors on mobile homes are often made from a foam-core sandwich material with vinyl or metal facing — less secure and less insulated than front doors. If your back door is original it is worth considering a quality insulated steel door. The back door opening is often a different size than the front — always measure separately and never assume they are the same.
Interior Doors
Interior doors in mobile homes are typically hollow-core and lighter than exterior doors. Common sizes are 28″ x 76″ for bedroom and bathroom doors and 24″ x 76″ for closets. Interior doors do not need weather sealing but do need accurate rough opening measurements — mobile home interior openings can be even less consistent than exterior openings between manufacturers.
Sliding Glass Doors
Sliding doors are popular in mobile homes because they do not swing into living space — helpful in tighter floor plans. Sliding door replacements are more complex than standard hinged doors and often call for a specialist. The track, frame, and glass panel sizes must all be matched precisely. See the guide on mobile home sliding doors for sizing, replacement options, and installation tips. Get professional measurement and installation quotes before ordering.
While you are measuring doors — it is a good time to inspect your mobile home windows as well. Drafty or damaged windows are often discovered during a door replacement project, and handling both at the same time can save on labor.
Would You Rather Sell Than Repair?
If the door is just one item on a growing list of doors, windows and other repairs, selling the home as-is is one option to compare. I buy mobile homes that need work, and you don’t have to fix anything first.
Frequently Asked Questions
What is the standard size for a mobile home door?
A very common exterior mobile home door size is 32 inches wide by 76 inches tall. Other common sizes include 34″ x 76″ for combination or storm doors and 36″ x 76″ for wider front doors on newer homes. Older homes built before 1980 may have 72-inch tall doors. There is no single universal standard — always measure your specific rough opening before ordering.
How do you measure a mobile home entry door?
Measure the rough opening — the width from inside wall stud to inside wall stud, and the height from the top of the opening to the floor. Take three measurements for each dimension and use the smallest. Also measure the frame depth (wall thickness), determine the swing direction (in or out), and note the handing (left or right). All six steps in the guide above are needed for a complete, accurate measurement.
Do mobile home doors swing in or out?
Unlike site-built homes where exterior doors almost always swing inward, mobile home exterior doors frequently swing outward. This is important because it affects where you take your measurements from — always measure from the opposite side to the direction the door swings. Check your specific door before measuring — not all mobile home exterior doors swing outward, and it varies by manufacturer and model.
Can I use a regular house door on a mobile home?
Generally not without modification. Standard house doors are 80 inches tall while mobile home doors are typically 76 inches. The frame depths, swing configurations, and rough opening sizes also differ. Forcing a standard house door into a mobile home opening means reframing, and a poor fit leads to drafts and energy loss. A door sized for mobile homes is usually the simpler choice.
How do I measure a storm door for a mobile home?
A storm door mounts on the outside of the existing door frame. Measure the width and height of the outside door trim — from the outside edge of trim on one side to the outside edge of trim on the other side, and from the top outside trim edge to the bottom sill. Take a photo of your tape measure in place and bring it to the store. 34″ x 76″ is a common storm door size for mobile homes, but your opening may differ.
Where can I buy replacement mobile home doors?
Mobile home doors are not typically stocked at big box hardware stores — those mostly carry standard house door sizes. Order from mobile home specialty suppliers, manufactured housing parts dealers, or online retailers who ship mobile home sizes. See the guide on exterior doors for mobile homes for a full breakdown of material options, styles, and where to buy.
