Tesla Model 3 Trunk Dimensions

The published figures are these: around 21.0 cu ft (594 L) with the rear seats up on a Model 3 Highland, rising to around 34.5 cu ft (977 L) with them folded, per EV Database's EU-market Long Range AWD entry. The frunk is published at about 3.1 cu ft (88 L). The 2017-2023 car is smaller behind the rear seats — commonly quoted at 15 to 16 cu ft — with the same 88 L frunk.

But the number that will actually decide whether something goes in your Model 3 is not in any of those tables. It is the size of the boot aperture, and on a saloon that is almost always the binding constraint rather than the floor.

The published volumes

The Highland's rear trunk is genuinely larger than the earlier car's, commonly reported as a gain of around 6 cu ft, and the frunk is essentially unchanged. That is a real improvement and it is the main cargo difference between the two generations.

Why the opening matters more than the floor

A Model Y has a liftgate: the opening is almost the full height and width of the cargo area, so if something fits in the space it generally goes in. A Model 3 has a boot lid, and the opening is a smaller rectangle set above and behind the floor. A suitcase that would sit happily on the floor can be impossible to get through the gap.

That is why owners who move from a Model 3 to a Model Y describe the cargo difference as far larger than the volume figures suggest, and why a Model 3 trunk organizer that assumes a wide flat floor is the wrong product. The useful shape here is tall and narrow, loaded through a restricted aperture.

What is verifiable and what is not

Measure your own, in two minutes

1. Step 1. The aperture first

   Measure the boot opening itself — width at its narrowest and height from the lip to the underside of the lid. Do this before anything else, because it is the number that rules items out.

2. Step 2. Floor length

   From the rear seat backs to the inside of the closed lid, along the floor.

3. Step 3. Width between the arches

   At the narrowest point. On a saloon this is tighter than the floor's overall width suggests.

4. Step 4. Depth to the parcel shelf

   Floor to the underside of the shelf or the lid's closed position, whichever is lower.

5. Step 5. The under-floor well

   Lift the trunk floor and measure the well. On a Highland this is included in the 594 L figure, which is one reason that number looks large next to the older car's.

1. Best for the shape it actually is

Model 3 trunk organizer

Yeslak

A Model 3 trunk is deep and narrow rather than wide, and this organizer is built for that rather than for an SUV cargo floor. Listed for both Highland and 2017-2023. It will not help with anything that will not pass the aperture.

Best for: Model 3 owners, whose trunk is deep and narrow rather than wide

Fits: Model 3 (2017-2023) · Model 3 Highland (2024-2026)

Overall8.2/ 10 — our editorial score, not a lab test

What works

• The Model 3 trunk opening is small, and a collapsible organizer fits through it where a rigid box does not
• Keeps shopping from sliding into the deep well under the floor

What does not

• Collapsible means it loses shape when empty
• Does not address the sub-floor well, which is where Model 3 space is really lost

Manufacturer specifications

• Shaped to the Model 3 trunk aperture and well
• Listed per Model 3 generation
• Collapsible construction

2. Best for the frunk

TAPTES frunk organizer for Model 3

TAPTES

Built for a Model 3 frunk, which is much shallower than a Model Y's at around 88 L. Both generations. Shallow means shallow: this is a divider for small items, not a second boot.

Best for: Model 3 owners, whose frunk is much shallower than a Model Y's

Fits: Model 3 (2017-2023) · Model 3 Highland (2024-2026)

Overall8.1/ 10 — our editorial score, not a lab test

What works

• Model 3-specific depth — a Model Y organizer simply will not close the hood
• Year-scoped listings rather than one Model 3 catch-all

What does not

• The Model 3 frunk is small enough that an organizer gives up real capacity to gain structure
• Shallow trays tip more easily than a deep box

Manufacturer specifications

• Shaped to the Model 3 frunk tub, which is notably shallower than the Model Y's
• Separate Highland and pre-Highland listings
• Molded tray with dividers

3. Best use of the front compartment

Insulated frunk cooler bag

TAPTES

An insulated bag is the right shape for a tapered frunk where a rigid box wastes the volume. Listed across both cars. No power and no compressor — it is a cooler bag, nothing more.

Best for: Groceries and tailgates, in the frunk rather than the cabin

Fits: Model Y (2020-2024) · Model Y Juniper (2025-2026) · Model 3 Highland (2024-2026) · Model 3 (2017-2023)

Overall8.1/ 10 — our editorial score, not a lab test

What works

• The frunk is the one compartment in the car with no cabin-air connection, so it is the right place for cold food
• A bag conforms to the tub where a rigid cooler fights it
• Lifts straight out to carry

What does not

• Insulation in a soft bag is modest — this is an hour or two of cold, not a day
• Takes most of the frunk, so it is not something you leave in permanently

Manufacturer specifications

• Insulated foam-lined bag sized to sit inside the frunk tub
• Used alongside a molded organizer rather than instead of one
• Zip closure

The frunk, briefly

At 88 L the Model 3 frunk is a genuinely small compartment — a little over half the Model Y's 117 L — and it tapers, so the usable volume is less than a box of that size implies. It is the right place for charging cables, a cooler bag and anything that might leak, and the wrong place for anything rigid and rectangular.

Owner measurements of a European display car put the Highland frunk opening at roughly 28.3 inches wide, 13.8 inches deep and 9.1 inches high. That is an owner measurement rather than a published figure, which is the standard caveat on almost every frunk number you will find anywhere.

For the equivalent exercise on the SUV, Model Y trunk dimensions and Model Y frunk dimensions cover the same ground with the same caveats. For organizers rather than numbers, Model 3 trunk organizers and Model 3 frunk organizers are the roundups.
