Tesla Model Y Trunk Dimensions

The published numbers are these: around 30.2 cu ft (854 L) behind the second row, and around 75.5 cu ft (2,138 L) with the second row folded on a 2025+ Juniper — 72.1 cu ft (2,041 L) on a 2020-2024 car. The frunk adds about 4.1 cu ft (117 L) and the well under the load floor about 2 cu ft. Those figures come from EV Database's EU-market Long Range AWD entries.

What is not published, by Tesla or by anyone else with a method we can check, is the length, width and depth of the tub itself. That is the measurement people actually want when they ask this question, and the honest answer is that the figures circulating online disagree with each other.

The published volumes, generation by generation

The Juniper's gain with the seats folded is the one real difference, and it has a mechanical explanation: the redesigned rear-bench folding geometry sits flatter against the floor pan. Seats up, the two generations are the same.

The tub measurements, and why we are not going to state them flatly

Third-party figures for the main cargo area put maximum depth at around 43 inches and minimum width at around 37 inches, with the sub-trunk well at roughly 27 inches wide, 18 inches front to back and 15 inches deep. Those come from an accessory retailer rather than from Tesla, the generation they apply to is not stated, and some other figures published alongside them are clearly wrong.

Measure your own, in two minutes

1. Step 1. Load floor length

   Tape from the back of the folded second-row seat to the inside of the closed liftgate, along the floor. This is the number that decides whether a bicycle or a flat-packed box goes in.

2. Step 2. Width between the wheel arches

   Measure at the narrowest point, not at the opening. The arches are the constraint, and this is the figure third-party sources quote most inconsistently.

3. Step 3. Height to the parcel shelf line

   Floor to the bottom of the rear glass. Anything taller than this is visible from outside and will not sit under a cargo cover.

4. Step 4. Liftover

   Ground to the lip. Relevant if you load anything heavy, or a dog that no longer jumps.

5. Step 5. Sub-trunk, all three dimensions

   Lift the load floor and measure the well itself. This is the space most owners underuse and the one no published figure describes usefully.

1. Best use of the measured space

Motrobe trunk mat and side-bin set

Motrobe

Covers the cargo floor and the side wells together, which is the shape the Juniper cargo area actually is rather than the rectangle a single mat assumes. Juniper only.

Best for: Juniper owners who want the cargo floor and the side wells covered together

Fits: Model Y Juniper (2025-2026)

Overall8.4/ 10 — our editorial score, not a lab test

What works

• Turns the side grooves — normally wasted space — into usable bins
• Juniper-specific, so it does not sit proud at the wheel arches the way a legacy part does

What does not

• Five-seat layout only; the seven-seat cargo floor is a different shape
• The bins reduce how flat the floor is when you want to slide something long in

Manufacturer specifications

• Built for the 2025-2026 Juniper five-seat cargo bay
• Side-bin design that uses the molded grooves either side of the cargo floor
• Wipeable surface

Specifications as published by the manufacturer. We have not independently tested this product.

2. Best without losing depth

3D MAXpider cargo liner

3D MAXpider

Protects the main cargo floor while costing almost none of the usable height, which matters on a car where the published volume is the selling point. Listed for 2020-2024 and Juniper.

Best for: Protecting the main cargo floor without losing usable depth

Overall8.3/ 10 — our editorial score, not a lab test

What works

• The raised loading-edge lip is what stops a spill running out onto the bumper
• Thin enough that you do not lose meaningful cargo height

What does not

• Covers the cargo floor only — the under-floor well needs its own piece
• Expensive for what is, functionally, one molded sheet

Manufacturer specifications

• Same three-layer construction as the footwell liners
• Shaped to the cargo well with a raised lip at the loading edge
• Separate part numbers per Model Y generation

3. Best for the sub-trunk

Under-floor storage bins (Model Y)

TAPTES

Divides the roughly 2 cu ft well beneath the load floor so it stops being a single pit. Both Model Y generations. It is a divider rather than a sealed container.

Best for: Dividing the deep well beneath the cargo floor

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

What works

• The sub-floor well is the single most wasted volume in a Model Y, and bins make it usable
• Everything stays below the load floor, so the cargo area still looks empty

What does not

• You have to lift the floor panel to reach anything, so it is for things you need rarely
• Bins reduce the well's total volume slightly

Manufacturer specifications

• Bins shaped to the sub-floor well under the main cargo floor
• Separate Juniper and legacy listings
• Rigid dividers with lift handles

What the numbers mean in practice

Thirty cubic feet behind the second row is a genuinely large figure for a vehicle this size, and the reason it works in practice is the depth of the tub rather than its footprint — the Model Y cargo area is deep relative to its floor area. That is why a tall-walled cargo tray is usually the wrong purchase here: the walls cost you the dimension the car is actually good at.

The sub-trunk is the other under-appreciated figure. Two cubic feet under a lid, out of sight, is the right place for anything you do not need until you stop, and it keeps the floor above it flat. Under-floor storage bins covers how to divide it.

For the front of the car, Model Y frunk dimensions applies the same approach to the frunk, which is the compartment with the least published data of all. For the Model 3, Model 3 trunk dimensions is the sedan equivalent of this page, and the shape of the problem there is completely different.
