How wide is a 1979 Ford F100?
A 1979 Ford F-100’s width depends on configuration and whether you count the body or the mirrors. In general, the body width is roughly 69 to 70 inches, and the overall width with factory mirrors is typically around 83 to 85 inches. Exact figures vary with cab style, bed length, and mirror setup.
Official figures and practical implications
Below are the common width figures you’ll encounter when researching a 1979 F-100, along with notes on what you might measure on your truck.
- Body width (fender-to-fender, no mirrors): about 69–70 inches (approximately 175–178 cm).
- Overall width with factory mirrors: about 83–85 inches (approximately 211–216 cm).
- With aftermarket or wider mirrors: the width can exceed 85 inches, depending on mirror design.
Several variables affect the exact numbers, including whether the truck has Regular Cab or other cab configurations, bed length, wheel/tire combination, and the specific mirrors fitted. If you’re planning parking space or garage clearance, measure your specific vehicle for precision.
Factors that can change the measurement
The 1979 F-100 generally shares a common body width across trims, while mirrors and bumpers add to the overall width. Some variation can occur between individual trucks due to production tolerances and aftermarket accessories, so catalogs may show slight differences from the actual vehicle.
How to measure the width on your own F-100
To get an exact figure for parking, storage, or trailer alignment, measure the installed width directly on your truck.
- Park on a level surface and engage the parking brake.
- Measure the distance from the outside edge of the left fender to the outside edge of the right fender at the widest point (usually near the front wheels), excluding mirrors.
- If you need the width with mirrors, measure from the outermost point of one mirror to the outermost point of the opposite mirror, following the widest span.
- Record both measurements and note tire size, rim width, and any aftermarket accessories that could widen the footprint.
These measurements help with garage openings, drive-throughs, and trailer hookups. For everyday planning, the body width is the most practical figure; use the mirror width only when you must account for visibility extents or parking space in tight spots.
Summary
In practical terms, plan for a body width around 69–70 inches and an overall width with factory mirrors in the 83–85 inch range for a typical 1979 Ford F-100. Exact numbers depend on configuration and installed equipment, so measuring your specific truck is the best way to ensure accuracy.
