Single wide homes provide an accessible path to ownership for budget conscious buyers and DIY oriented builders. These factory built units ship in one section, making delivery, permitting, and site work more straightforward than modular alternatives.
Understanding exact single wide sizes helps you match a floor plan to your lot, avoid surprise site work, and compare quotes from multiple manufacturers. The following sections break down standard widths, lengths, and height clearances you will encounter.
| Standard Width | Typical Length Options | Overall Height Limit | Common Bedroom Count |
|---|---|---|---|
| 14 feet | 48 ft, 56 ft, 64 ft | 13 ft 6 in | 1 to 3 |
| 16 feet | 48 ft, 56 ft, 64 ft, 72 ft | 13 ft 6 in | 2 to 4 |
| 18 feet | 48 ft, 56 ft, 64 ft, 72 ft | 13 ft 6 in | 2 to 4 |
| 20 feet | 60 ft, 64 ft | 13 ft 6 in | 3 to 5 |
Standard Single Wide Widths and Depth
Manufacturers follow regional overpass and bridge regulations, so standard widths cluster at 14, 16, 18, and 20 feet. Choosing among them depends on road access, garage integration, and the number of rooms you want.
Depth or length typically ranges from 48 ft to 72 ft, with 64 ft being a common sweet spot for larger families. Longer depths allow for extended living rooms, formal dining areas, and generous kitchen layouts without sacrificing bedroom space.
When evaluating depth, factor in driveway length, garage capacity, and local transport rules. A 16 foot wide, 64 foot long unit often fits well on medium sized residential lots, while 18 and 20 foot widths may require a longer, flatter site.
Height, Transport, and Site Clearance Rules
Overall unit height is usually capped at 13 ft 6 in to meet overpass and driveway clearance rules. Verify local bridge and underpass heights if your route to the site includes older urban infrastructure.
Transport width determines whether a truck can use standard highways without special permits. Units up to 16 feet wide travel on public roads, while 18 and 20 foot models sometimes need escorts or temporary lane closures depending on state regulations.
Site clearance includes not only overhead wires but also underground utilities, slope, and access road turning radius. Work with your installer to survey these before the delivery date to avoid costly repositioning.
Room Layout Efficiency Within Fixed Widths
Within a given width, architects can vary room counts by using open plan living areas or compact bedroom suites. A 14 foot unit may comfortably hold a bedroom, bathroom, kitchen, and living room if the depth is generous.
Increasing to 16 or 18 feet often enables a separate formal living room, larger kitchen island, and an optional second bedroom. This extra width also allows more breathing room between the master suite and shared spaces.
Compare floor plans at identical lengths but different widths to see how hallway and wall thickness affect usable square footage. Some designs sacrifice a narrow hallway to integrate a bedroom into an open plan for a cozier flow.
Cost, Warranty, and Builder Licensing Considerations
Pricing generally rises with width and length because material use, transport fees, and crane requirements increase. However, wider units can reduce site preparation costs by simplifying deck sizing and foundation runs.
Factory warranties differ by manufacturer and panel configuration, so review transferability, appliance coverage, and structural guarantees. Longer units may include additional anchors and tie downs that affect the warranty terms.
Local builder licensing rules can impact who is allowed to install or modify single wide homes. Confirm that your chosen installer holds the appropriate endorsements for the specific width and foundation type you select.
Key Takeaways for Choosing Single Wide Sizes
- Match standard widths (14, 16, 18, 20 ft) to your road access and local overpass limits.
- Prioritize depth between 60 ft and 64 ft for flexible layouts in larger families.
- Confirm height, transport, and site clearance rules before placing an order.
- Compare floor plans at identical lengths but different widths to maximize usable square footage.
- Factor transport, permits, and site prep into your total project budget.
FAQ
Reader questions
What is the narrowest standard single wide that still allows a full kitchen and two bedrooms?
A 14 foot wide unit can support a full kitchen and two bedrooms when the depth is 64 ft or more, using compact appliance layouts and efficient space planning.
Can a 16 foot wide single wide fit through most overpasses on highway routes?
Yes, a 16 foot wide unit typically clears standard highway overpasses without special permits, but you should verify exact vertical and horizontal clearances on your delivery route.
How does increasing depth from 48 ft to 72 ft affect living space quality in a single wide home?
Deeper units provide a more balanced layout with longer hallways, larger living and dining areas, and the option to add an office or third bedroom without shrinking the kitchen.
What additional site costs should I expect when ordering an 18 foot wide single wide?
Expect higher transport fees, possible road prework, larger concrete pads, and possibly a crane rental, since many local codes require extra anchoring for wider sections.
