Can a 4×8 sheet of plywood fit in a 5.5-ft bed?

Not flat — a 5.5-ft bed (66") is 30" short of 8 ft. You need the tailgate down and a bed extender, or angle it diagonally. A 6.5-ft bed handles plywood with just the tailgate down.

What's the real difference between 5.5, 6.5, and 8-ft beds?

Usable floor length: about 67", 79", and 98". The 6.5-ft is the sweet spot for most hauling — it fits a standard sofa (84") with the tailgate down. The 8-ft bed is for full sheets, lumber, or commercial loads.

“Confirmed my 65" TV fits in the RAV4 before buying. Would've been stuck at the store.” — Weekend project

Measure smart

What to measure.

Four numbers decide nearly every fit check. Get these right and the rest follows.

01Measure the longest item — this determines minimum bed length
02Check bed width between wheel wells (typically 50–52" vs. 64–66" at the top)
03Factor in tailgate-down length if items can hang over — adds ~18–21"

Don't make these

Common mistakes.

Most “it didn't fit” stories trace back to one of these oversights.

⚠Measuring bed length at the top — the floor length is shorter due to the bulkhead angle, often 2–4" less than the spec sheet
⚠Forgetting wheel well intrusion — between the wheel wells you lose 12–16" of width compared to the full bed width
⚠Assuming items can ride tailgate-down safely — anything past 2 ft overhang needs a flag and secure strapping
