The F-150 is the truck this site sees most, and it has three fitment characteristics that matter more than anything else when you are buying gear: three bed lengths, an aluminum body, and a factory options list long enough that two identical-looking trucks can take different parts.
The two numbers to carry around: your exterior bed rail width is about 65 inches, and the interior width between the wheel wells is 50.6 inches. Almost every fitment question comes back to one of those.

Those are the published figures. Measure your own truck as well, because a bonded rail cap or a drop-in liner changes what a box actually lands on — the published number is the bed, not your bed with the liner in it.
Heavy-wall aluminum, a foam-filled RigidCore lid that does not flex when you sit on it, and a low profile that still clears most rear glass. This is the crossover to buy if you intend to keep the truck.
Who should skip it. Skip it on a 5'5" short bed. At 69 inches it will sit on the rails, but you lose a disproportionate share of a short bed and the money is better spent on a side-mount pair.

What works
+Foam-filled lid does not oil-can under body weight
+Low profile clears rear glass on most full-size crew cabs
+Heavy-wall extrusion survives being used as a step
+Gas struts are serviceable rather than sealed units
What does not
−Among the most expensive aluminum crossovers on the shelf
−69 in is a full-size length — not a mid-size answer
Two full-length weather-sealed drawers under a load-bearing deck. You keep the whole bed floor on top and gain two drawers you can reach from the tailgate without climbing in, which is the single biggest day-to-day change you can make to a work truck.
Who should skip it. It raises your bed floor by the height of the drawer module, so you lose vertical space and the ability to carry a full-height pallet. If you haul bulk more than tools, this is the wrong buy.

What works
+Drawers are reachable from the tailgate — no climbing into the bed
+Deck surface stays usable for cargo on top
+Weather-sealed drawers keep tools dry in an open bed

What does not
−The most expensive item in this category by a wide margin
−Raises the bed floor and costs you vertical capacity
−Very heavy — payload matters if you also tow
−Sold per bed length; ordering the wrong one means a return freight bill
WeatherBeater is the liner most people should buy. It gives up a little wall height to WeatherTech and costs substantially less, and in daily use the difference shows up about twice a winter.
Who should skip it. If you track mud and meltwater in by the shovelful, the lower sill wall is a real limitation and WeatherTech earns its premium.
A frame that mounts into the bed's stake pockets with no drilling and puts real steel between the cab glass and whatever is in the bed. If a ladder shifts, this is the difference between a scare and a windscreen through the cab.
Who should skip it. The frame is sold frame-only. Hardware kits, lights and the tool-box mounting kit are extra, and the total adds up fast.

A five-piece drop-in that covers floor and sides. Drop-ins are unfashionable and they still make sense: the bed sheet metal never gets touched, and when the liner is destroyed you replace the liner instead of repainting the truck.
Who should skip it. Grit gets between a drop-in and the bed and sands the paint. If the truck is going to be sold on condition, a spray-in is the safer choice.

Other bed lengths
Tool boxes
At roughly 65 inches of exterior rail width, the F-150 takes standard full-size crossover boxes — the 69 and 72 inch size classes. That is the widest product selection of any format and it is where most F-150 owners should start.
The constraint is bed length rather than width. On a 5.5 ft bed a 19-inch-deep crossover box eats a meaningful share of a 67.1 inch floor, which is the case for a narrow-body box or a side-mount box instead. On a 6.5 ft or 8 ft bed it is a non-issue.
Drawer systems are sold per bed length for this truck and the length has to be exact. At 50.6 inches between the wheelhouses, the F-150 takes the standard full-size drawer modules and the 48-inch-wide bed slides without a fight.
Drawer systems. Order for your exact bed — 5.5, 6.5 or 8 ft. See drawer systems.
Bed slides. 48 in wide fits the 50.6 in well width with room for the rails. See bed slides.
Cargo bars. A 40-70 in bar covers the F-150's interior width comfortably. See bed dividers.
Anchors. Check whether your truck has usable stake pockets before buying stake-pocket D-rings. See tie-downs.
Protection
Two F-150-specific things to know. First, the aluminum body changes nothing about accessory fitment but it does mean corrosion behaves differently — galvanic reactions at dissimilar-metal fasteners are a real consideration, so use the hardware that comes with the part.
Second, the electric F-150 has different bed hardware — charge outlets, tie-down positions and drain locations — so a bed mat or liner cut for the gas truck can have the wrong cut-outs. Listings that cover both state it explicitly; assume one that names only the gas truck does not.
Tonneau covers. Sold per bed length and per model-year range, with the 2015-2020 and 2021-onward trucks taking different parts. See tonneau covers.
Bed liners. Watch for the Pro tailgate exclusion. See bed liners.
Mud flaps. Front and rear sets exist; front flaps are the ones that protect the rocker. Raptor is excluded from most. See mud flaps.
Running boards. Cab-specific. SuperCrew, SuperCab and Regular Cab all take different lengths. See running boards.
Racks
The F-150 is unusually well served here, and the reason is stake pockets: the no-drill headache racks mount into them, and the no-drill clamp ladder racks grip the rail lip. Both are available for an exceptionally wide model-year range on this truck.
The combination that trips people up is a rack plus a crossover box, which is set out in ladder rack with a tool box. On a 5.5 ft bed, that combination is tight and the honest answer is often to pick one.
Interior
Seat covers are sold per seat configuration rather than per truck, and the F-150 has several — buckets, 40/20/40 bench with a fold-down center, powered and manual. Work truck seat covers covers what to check.
Floor liners are sold per cab, and the exclusion that catches F-150 owners is fold-flat rear floor storage: several liners do not fit trucks with it. All-weather floor liners has the picks, and the under-seat void on a SuperCrew is the best storage space in the truck — see cab organizers.
Fitment detail
Everything for this truck
The published dimensions, the tool box size that fits, and the roundup built around both.
A standard full-size crossover box — the 69 or 72 inch size class. The F-150's exterior bed rail width is about 65 inches, which is what those boxes are designed around. Confirm against your own measurement and the manufacturer's fitment chart. Full answer.
How wide is an F-150 bed between the wheel wells?
50.6 inches, per Ford's published specifications, and the figure is the same across all three bed lengths. That is the number that matters for chests, drawer modules and bed slides sitting on the floor.
How long is each F-150 bed?
At the floor: 67.1 in for the 5.5 ft bed, 78.9 in for the 6.5 ft bed and 97.6 in for the 8.0 ft bed. Cargo volumes are 52.8, 62.3 and 77.4 cu ft respectively. Full table with sources.
Does the F-150 Lightning take the same bed accessories?
Not always. The electric truck has different bed hardware — charge outlets, tie-down positions and drain locations — so mats and liners cut for the gas truck can have the wrong cut-outs. Listings covering both say so explicitly; assume one that names only the gas truck does not.
Can I fit a tool box and a tonneau cover on an F-150?
With a slimline or low-profile cross-bed box and a cover notched for a tool box, yes. With a standard 14 in crossover box and an ordinary cover, no. On a 5.5 ft bed the combination is tight enough that picking one is often the better answer. Clearances.
