Enter your mattress size and truck bed measurements — the app checks bed length, width, and tailgate-down options.
Twin and full mattresses fit flat in most truck beds. A queen (60"×80") fits in standard and long beds with tailgate up, or in short beds with tailgate down. King (76"×80") requires a standard or long bed and overhangs the sides. Always use a mattress bag and ratchet straps.
Mattress length vs. truck bed length, and mattress width vs. bed width between wheel wells
Item: Twin: 38"×75". Full: 54"×75". Queen: 60"×80". King: 76"×80"
Space: Short bed: 65" L × 52" W (wheel wells). Standard bed: 78" L × 52" W. Long bed: 97" L × 52" W
Tip: Use ratchet straps and a mattress bag — wind can lift an unsecured mattress off the bed at highway speeds.

A queen mattress (60" × 80") does not fit flat in a short bed (65" long) with the tailgate up — it's 15" too long. With the tailgate down, the mattress overhangs about 15–18" which is manageable for short trips. The 60" width sits above the 52" wheel wells with slight overhang on each side.
A king mattress (76" × 80") fits in a standard bed (78") or long bed (97") with the tailgate up. In a short bed (65"), the king overhangs 15" even with the tailgate down. Width-wise, the 76" king is wider than the truck bed (64") and will overhang the sides — use side rails or a bed extender for support.
Use at least 4 ratchet straps (not bungee cords) looped through the bed tie-down hooks. Crisscross two straps over the top to prevent wind lift. Place the mattress in a waterproof mattress bag first. For highway driving, add a cargo net on top. Never rely on the mattress's weight alone — wind will lift it.
Absolutely — truck beds expose mattresses to rain, road dust, insects, and debris. A mattress bag costs $10–$20 and is essential for any distance over a few blocks. Seal the bag completely with tape. Even on a sunny day, road grime and truck bed residue will stain an unbagged mattress.
A 6-foot truck bed handles most furniture the open-air way. Here's what fits in short, standard, and long beds — plus how to secure it safely.
A queen mattress is 60 × 80 inches. Most SUV cargo areas are shorter than 80 inches. Here's which SUVs actually work — and the tricks that make it possible.
