Can a King Size Mattress Fit in a Cargo Van? Practical Answers and Key Measurements

If you’re planning a move or pickup, it’s natural to ask: Can a king size mattress fit in a cargo van? The short answer is: often yes, but it depends on both the mattress type and the specific van’s interior dimensions.

This FAQ-style guide walks through what you need to measure, common fit issues, and simple tips to make transport safer and easier.

What Are the Typical Dimensions of a King Size Mattress?

A good starting point is knowing exactly what you’re trying to move.

Most standard king size mattresses measure approximately:

  • 76 inches wide x 80 inches long
  • Thickness can vary, often 10–14 inches or more

Some variations include:

  • California king: usually 72 inches wide x 84 inches long (narrower but longer)
  • Split king: two separate pieces, each similar to a twin XL
    This is much easier to move than a one-piece king.

When asking “Can a King Size Mattress Fit In a Cargo Van”, keep both the length and width in mind, and remember that diagonal placement can help in some vans.

How Big Is a Typical Cargo Van Inside?

Cargo vans vary a lot by model and size category. Instead of relying on a single number, look at three key interior dimensions:

  • Length: distance from the back doors to the divider or front seats
  • Width: side-to-side, and especially width between wheel wells
  • Height: floor to ceiling (if you plan to stand the mattress up)

Many standard cargo vans have:

  • Enough interior length to lay a king mattress flat or diagonally
  • Enough width between wheel wells for the 76" mattress width to fit upright or at an angle
  • Enough height to stand the mattress on its side in some models

However, compact or small cargo vans may be too short or narrow for a king mattress to lie flat. In those cases, you might only be able to angle or stand it up.

Can a King Size Mattress Fit in a Cargo Van Lying Flat?

In many full-size cargo vans, yes, a king mattress can lie flat, but it’s not guaranteed.

It is more likely to fit flat if:

  • The interior length is at least 80 inches (preferably more, to allow for slight bending or a box spring if included)
  • The usable width is at least 76 inches in the area where the mattress will rest
  • There are no large obstructions, shelves, or partitions in the way

If the van’s length is slightly shorter than 80 inches, some mattresses can flex slightly to fit, especially all-foam designs. However, very rigid or thick hybrid and innerspring mattresses may not bend comfortably without risk of damage.

Is It Better to Stand the Mattress on Its Side?

Many people transport a king mattress on its side in a cargo van to save floor space.

This can work when:

  • The interior height is greater than 76 inches
  • The mattress is secured so it does not tip or fold
  • There are tie-down points, straps, or other items to brace it against

Standing the mattress on its side often makes it easier to accommodate other items, but it should be secured well to avoid shifting during transit.

How Do I Check if My King Mattress Will Fit Before the Trip?

Before you load, a quick set of measurements can prevent surprises.

✅ Quick Measurement Checklist

Measure inside the cargo area:

  • Interior length (back doors to bulkhead or seats)
  • Interior height (floor to ceiling)
  • Width between wheel wells
  • Widest interior width (higher up the walls, if the van curves)

Then compare with:

  • King mattress: about 76" x 80"

👉 If either interior length or diagonal length is at least 80", and one dimension is at least 76", there is a good chance you can make it work (either flat or angled).

What About Folding or Bending a King Mattress to Make It Fit?

Whether you can fold a mattress safely depends heavily on its construction:

  • All-foam mattresses: often more flexible, may bend or slightly fold to fit
  • Hybrid or innerspring mattresses: usually less flexible; sharp bending or tight folding can damage internal components

As a general guideline, avoid forcing a mattress into a shape that creates a hard crease, especially for spring designs. Light, temporary flexing to clear a door frame or angle into the van is usually more acceptable than folding it in half.

Do I Need Any Special Supplies to Move a King Mattress in a Cargo Van?

Having a few basic items makes transport smoother and safer:

  • Mattress bag or cover to protect from dirt and moisture
  • Moving straps or rope to keep the mattress from sliding
  • Blankets or padding between the mattress and van walls
  • Dollies or sliders if moving through hallways or elevators

These help prevent tears, scuffs, and sagging while the mattress is in transit.

✔️ Quick Mattress Takeaways

Key points consumers should understand about “Can a King Size Mattress Fit In a Cargo Van”

  • A standard king mattress is about 76" x 80", so the van’s interior must accommodate at least these dimensions.
  • Many full-size cargo vans can fit a king mattress flat or on its side, but compact cargo vans may not.
  • Always measure interior length, height, and width between wheel wells before transport.
  • Standing the mattress on its side can work if the van’s height is at least 76" and the mattress is well secured.
  • All-foam mattresses are typically easier to flex into tighter spaces than innerspring or hybrid designs.
  • Avoid tight folding or sharp bending that may damage the mattress.
  • Using a protective bag and straps helps keep the mattress clean and stable during the move.

Understanding the true size of your king mattress and the exact interior dimensions of the cargo van makes it much easier to answer the question, “Can a King Size Mattress Fit In a Cargo Van?” With a tape measure, a few minutes of planning, and some basic moving supplies, you can usually determine the best and safest way to transport your mattress with confidence.
