How Big Is a 1:64 F1 Car? Size, 2026 Rules and Case Fit

1:64 F1 car size: length, width, height and wheelbase

The FIA rules limit an F1 car's width and wheelbase but set no overall length, so any true-scale length for an F1 diecast at 1:64 has to start from team and press figures. The table divides each published figure by 64; for what 1:64 means and how true-scale sizes work, see our 1:64 scale size guide.

Wheelbases marked "up to" are given only as a maximum, by the team or by the rules.

Two things stand out. First, modern F1 cars are long for 1:64: the 2026 cars come out at 85–86 mm, while the 2004 Ferrari is 71.0 mm. Second, every car in the table is about 15 mm tall at true scale, because a real F1 car is under 1 m high. For the 2022–25 generation we found no team length except the C43's "over 5,500 mm". F1 Chronicle puts those cars at "approximately 5,700mm" in one place and "5,600 to 5,800mm" in another, which would be 87.5–90.6 mm at 1:64; treat these as press estimates, not team figures.

What the 2026 F1 rules changed (and what that means at 1:64)

For 2026 the FIA cut two of the car's fundamental dimensions. Article C2.3 of the 2026 Technical Regulations (Section C, Issue 11, published 26 February 2025) says that, except for the tyres and wheel rims, "no part of the car may lie more than 950mm from the plane Y=0", the car's centre line. That is a maximum width of 1,900 mm. The same article says the wheelbase "must be less than or equal to 3400mm".

The 2022–25 cars were allowed 2,000 mm of width and a wheelbase of up to 3,600 mm, the limits F1 Chronicle gives for that generation and the figures on Sauber's 2023 spec page. So the 2026 car is 100 mm narrower and its wheelbase limit is 200 mm shorter.

At 1:64 that is small: 100 mm of width is 1.6 mm, and 200 mm of wheelbase is 3.1 mm. The rules still do not cap overall length; the same press source writes that "The FIA does not define a single maximum overall length in its Technical Regulations". The two 2026 lengths we found, 5,440 mm for the Audi R26 and under 5,505 mm for the Mercedes W17, work out at 85.0 mm and under 86.0 mm. If a 2025 and a 2026 model on your shelf differ by much more than a few millimetres, the rule change is not the reason: the models were made to different sizes.

Which brands sell F1 cars as 1:64, and what to check on the listing

Two well-known diecast brands list F1 cars labelled 1:64 on their own shops. What follows is what those pages said when we checked them on 5 October 2026; ranges change every season.

• Hot Wheels (Mattel). The Hot Wheels F1 assortment page describes a "Premium Formula 1® race car in 1:64 scale, plus a display plinth and specialized packaging", with a metal body and chassis, and lists "16 unique Formula 1 race cars featuring 2024 liveries". Mattel says it is "designed for adult Formula 1® fans and Hot Wheels collectors". The toy packs are a different line: a 10-pack "includes all 10 racing team cars from the 2025 Season in 1:64 scale", is for ages 3+ and is listed as compatible with Hot Wheels Racing F1 track sets, and a 5-pack is described as "1:64 scale die-cast Formula 1 race cars", also for ages 3+.
• Bburago. Bburago's 1:64 collection lists 2025 F1 cars "with display case" (on the Italian-language listing, "con teca espositiva"): the Ferrari SF-25, McLaren MCL 39, Mercedes-AMG F1 W16 and Red Bull RB21. Bburago also sells F1 cars at 1:43, including Ferrari SF-24 and SF-25 models and pit-stop playsets, so a search for "Bburago F1" mixes both scales.

Neither brand's page gives a car length in millimetres, and we did not measure any of these castings, so we can't say how close they are to true scale. A "1:64" on a Hot Wheels package is not a promise of exact scale either; our guide to what scale Hot Wheels are explains why.

The 1:43 mix-up is the bigger risk. The same team car at 1:43 is half as long again: a 5,440 mm car is 126.5 mm at 1:43 against 85.0 mm at 1:64, far too long for a 90 mm interior. Before you buy, check three things on the listing:

• The scale in the title or on the box: 1:64, not 1:43.
• A length in mm, if the seller gives one.
• "With display case" or "plinth": the package is bigger than the car, so judge the car on its own.

Will a 1:64 F1 car fit our case?

We make the Kicar Pocket Case, a 1:64 diecast keychain case with a 90 × 38 × 25 mm interior. The car sits on a base plate that screws into the case.

With an F1 car, start with length, not height. A true-scale 2026 car at about 85–86 mm leaves about 4–5 mm of the 90 mm. A 2022–25 car can be longer: the only team figure we found (C43, over 5,500 mm) gives at least 85.9 mm, and one press source's 5,600–5,800 mm would be 87.5–90.6 mm. At the low end that should still fit, from about 89 mm it is tight, and at the top of the range it is too long for the case. A real car longer than 5,760 mm would be over 90 mm at true scale.

Width leaves more room: about 29.7 mm of bodywork for a 2026 car and 31.3 mm for the 2,000 mm-wide C43, in a 38 mm interior. Tyres and rims sit outside the FIA width rule, so measure across the wheels too. Height is rarely an issue at about 15 mm, but the usual rule still applies: the car, including the rear wing and airbox, needs to be under 25 mm tall, ideally with about 1 mm to spare.

The two ends are where an F1 car meets the case. The press figure for the W17 runs "from the tip of its front wing to the trailing edge of its rear bodywork", and the wing tips are thin parts on a small casting. The car is held on the base plate with a rubber band and a wire band, and the plate screws into the case. Centre the car on the plate so both ends have the same room.

To check your own car, take four steps:

1. Find the length. Use a length in mm from the box or listing. If there is none, lay the car on a ruler and read from the front-wing tip to the rearmost point.
2. Compare it with 90 mm. Under 89 mm: it should fit lying flat. 89–90 mm: tight, under 1 mm to spare, so try it gently. Over 90 mm: too long for the case.
3. Check the wings and wheels. Look at the wing tips and the widest point across the tyres; the width needs to stay under 38 mm.
4. Take it off any plinth or base. Only the car goes on the base plate; a display plinth adds length and height you don't need.

The same check works for any case or shelf; the fit section of our size guide walks through it for road cars, and our 1:64 truck size guide covers other long castings.
