2021 Tesla Model X exterior dimensions
The 2021 Tesla Model X is large by crossover standards. Its biggest departure from the average crossover is its 505.7cm length, which is around 53cm, or 12%, greater than the class norm. The 199.9cm width excluding mirrors is 15cm, or 8%, wider, increasing to approximately 21cm, or 10%, with the mirrors extended. Short or narrow parking spaces are therefore likely to expose its size quickly. Its 168cm height is around 5cm, or 3%, above average, while the 296.5cm wheelbase is approximately 24cm, or 9%, longer. Overall, its length and width create a footprint of about 10.1m², roughly 1.7m², or 20%, larger than that of the average crossover.

DriveSize footprint score
DriveSize footprint score compares this car's footprint with the average footprint for the same class.
A score near 100% means it is close to class average size. Lower scores mean it sits further from that average, either smaller or larger.

Fast facts
Fast facts
Everyday SAE cargo space is 50% above average
With all five seats occupied, the Model X provides 1,111 litres of cargo capacity, around 372 litres more than the average crossover for shopping, luggage or other regular loads.
Its cargo efficiency is 20% above average
Combining the seats-up and maximum figures, the Model X provides about 157 litres per square metre of ground space, around 20% more than the crossover norm.
Only half of the regional spaces physically fit it
Four of the eight standard parking spaces tested by DriveSize can contain the Model X, while only USA/Canada provides comfortable surrounding room.
It is 43% heavier than average
The Model X weighs 2,337kg, approximately 705kg more than the typical crossover.

Cargo space & efficiency
2021 Tesla Model X cargo capacity and space efficiency
When all five seats are in use, the Model X provides 1,111 litres of published SAE cargo capacity. That is around 372 litres, or 50%, above the crossover average, giving it substantial extra room for family luggage, shopping or other everyday loads without folding the back seats. Maximum SAE capacity reaches 2,471 litres, approximately 600 litres, or 32%, above average, while a separate 183-litre front boot (frunk) provides another storage area. This gives the Model X an advantage for both everyday use and larger loads. Combining its seats-up and maximum cargo figures, the Model X provides about 157 litres per square metre of ground space. That is roughly 20% above average for a crossover, so its larger exterior is paired with above-average cargo efficiency.

Parking
Will the 2021 Tesla Model X fit in a standard parking space?
The Model X can physically fit within four of the eight standard regional parking spaces tested by DriveSize below. Although USA/Canada is the only bay that also leaves enough surrounding room for comfortable entry and exit. China, Australia and the Middle East can contain the car but remain restrictive. The Model X is too long for the United Kingdom, European Union, India and Japan spaces, making location an important consideration for regular parking.
DriveSize parking fit score
DriveSize compares the car's width and length with typical parking-space sizes by region.
Vehicle dimensions are rounded up and available side or length clearance is rounded down.
Side clearance is based on body width excluding mirrors where available; real spaces can vary because of mirrors, walls, pillars, kerbs, bay markings, and nearby cars.
For an average USA / Canada space: body side clearance is 37.5 cm per side (excluding mirrors), and length clearance is 22 cm at each end.

Usability
2021 Tesla Model X usability & manoeuvrability
The 12.3m turning circle is around 1.1m, or 9%, wider than the crossover average. It consequently needs extra room for U-turns, tight corners and changing direction in confined car parks. Its 2,337kg kerb weight is approximately 705kg, or 43%, above average. Ground clearance is 14.6cm, around 3.5cm, or 19%, below the crossover norm, so drivers would need to take more care over tall speed humps, abrupt ramps and uneven roads.

DriveSize overview: 2021 Tesla Model X
Looking at its dimensions and capacities, the 2021 Tesla Model X may suit drivers who want a five-seat crossover with unusually generous cargo space. Its everyday SAE capacity is 50% above average, maximum capacity is 32% higher and its combined cargo efficiency is around 20% above the class norm.
That carrying ability comes in a demanding exterior package. Its footprint is approximately 20% larger than average, only four of the eight tested regional parking spaces physically fit it and its turning circle is 9% wider. Its 19% lower ground clearance is another consideration on abrupt ramps or uneven surfaces.
The earlier seven-seat 2015 Tesla Model X has virtually identical exterior dimensions.
