Tesla Model 3 Legacy Frunk Dimensions (2017–2023)
The 2017–2023 Tesla Model 3 Legacy frunk is useful, but it is small enough that shape matters more than raw volume. Below we separate published volume, owner-measured opening dimensions, and practical load limits so you can decide what belongs up front instead of forcing cargo into the rear trunk.
At a Glance — Legacy Model 3 Frunk Numbers
| Metric | Imperial | Metric |
|---|---|---|
| Frunk cargo volume | 3.1 cu ft | 88 L |
| Owner-measured Legacy frunk opening, W × H × L | 28 × 7.9 × 15 in | 71 × 20 × 38 cm |

What Fits in the Front Trunk?
Use the Legacy frunk for dense, compact items: a mobile connector bag, one soft backpack, small grocery bags, a coiled charging cable, or a fitted liner that can be lifted out for cleaning. The 88 L / 3.1 cu ft volume sounds generous on paper, but the 20 cm / 7.9 in measured height is the real limiter.
Soft-sided cargo works better than hard cases. A cable bag, microfiber kit, compact pump, or groceries can settle into the tapered floor without pressing on the tub lip.
Dimensions vs. Rear Trunk Storage
| Storage zone | Best use | Tradeoff |
|---|---|---|
| Front trunk | Charging gear, groceries, detail towels, soft day bag | Height is limited; hard luggage is usually too tall. |
| Rear trunk upper floor | Luggage, stroller frame, sports bags | Shared with daily cargo, so dirty gear can mix with groceries. |
| Rear lower tub | Tools, emergency kit, infrequent-use storage | Requires lifting the cargo floor to access. |
| Frunk mat or liner | Protecting the plastic tub from wet bags or dusty cables | Remove and rinse separately; do not trap standing water underneath. |
Use the frunk for separation: keep wet, dusty, or cable-related items up front, and reserve the rear trunk for luggage.
Weight Cap and Packing Notes
For load planning, use 110 lb / 50 kg as the current front-trunk cap reported from Tesla's updated manual guidance. Weight should sit flat in the tub, not on the plastic lip or latch area.
Avoid loose metal tools, sharp recovery gear, or bottles that can leak. If you carry charging equipment up front, use a bag or molded liner so the cable head does not rub directly against the frunk wall.

Frequently Asked Questions
How big is the 2017–2023 Model 3 frunk?
The commonly cited volume is 3.1 cu ft, or 88 L. Owner-measured Legacy dimensions published by TeslaNorth put the opening near 71 cm wide, 20 cm high, and 38 cm long. That shape favors soft bags, charging cables, groceries, and fitted mats rather than hard suitcases.
What is the Model 3 frunk weight limit?
For current load planning, use 110 lb / 50 kg as the front-trunk cap reported from Tesla's updated manual guidance. In real use, we would still distribute weight flat across the tub and avoid sharp objects pressing into the latch side or plastic wall.
Does the Legacy frunk fit a carry-on suitcase?
Most rigid carry-ons are too tall or too square for the Legacy frunk because the measured height is only about 7.9 in / 20 cm. A soft overnight bag or compressible backpack is more realistic. Put roller luggage in the rear trunk instead.
Is the 2017–2023 frunk the same as Highland?
No. Highland changed the front-end packaging and owner measurements show a slightly taller, deeper frunk. Flexible bags may transfer, but molded frunk liners should stay generation-specific. For this page, Legacy means 2017–2023 Model 3 with physical stalk controls.
Should charging cables go in the frunk or rear trunk?
The frunk is a clean place for charging cables because it keeps grit away from luggage and groceries. Use a cable bag or frunk mat so the connector does not scuff the tub. If the cable is wet, dry the liner instead of closing moisture under it.
