BMW 3 Series data analysis

How BMW 3 Series overall length varies

Across 68 configurations recorded for the 2015 through 2026 BMW 3 Series, overall length runs from 182 inches to 190 inches. The strongest figure belongs to the 2015 BMW 3 Series (3 SERIES 328i xDRIVE Gran Turismo) at 190 inches, and the weakest to the 2019 car (3 SERIES TOURING 330i xDRIVE 4DR WAGON) at 182 inches — a spread of 4%. The narrow spread means any year of the BMW 3 Series in this table behaves much like the others, so you can shop on price, condition and mileage rather than chasing a particular model year.

What changed for 2026

Average overall length for the 2026 BMW 3 Series is 185 inches, against 185 inches for the 2025 car — it held flat. A carry-over year like this usually means no powertrain or structural change, so an older example is the cheaper way into the same specification.

How to read this BMW 3 Series data

This page lists every 2015 through 2026 BMW 3 Series record we hold for this measurement — 68 rows in total, one per configuration and model year rather than a single headline figure. Figures are published as the source agency records them: we do not round, average or interpolate missing years, and a year that is absent from the table is a year with no published measurement rather than a zero. Where a manufacturer offered several drivetrains or body styles in the same year, each appears on its own row, because those variants rarely share the same numbers.

Configurations behind these BMW 3 Series numbers

The 2015 through 2026 BMW 3 Series entries here cover variants including 3-SERIES M340i xDRIVE 4DR SEDAN, 3-SERIES 330i xDRIVE 4DR SEDAN, 3-SERIES 330e 4DR SEDAN, 3 SERIES TOURING 330i xDRIVE 4DR WAGON, 3 SERIES 340i xDRIVE Gran Turismo, 3 SERIES 330i xDRIVE Gran Turismo, 3 SERIES TOURING 328d xDRIVE 4DR WAGON and 3 SERIES 340i xDRIVE 4DR SEDAN. 2015 is the busiest model year in the record with 12 separate measured configurations, which is why a single quoted overall length figure for that year is rarely the one that matches the car in front of you. Match the row to the exact drivetrain, body style and engine on the window sticker or VIN before relying on the number, and use the comparison links below to see how those same configurations line up against rival models.

Where these BMW 3 Series figures come from

Every value on this page is loaded from federal open data — EPA fuel economy submissions, NHTSA vehicle and crash-test records, and manufacturer specification filings — rather than dealer listings or copied editorial content. The BMW 3 Series record refreshes as the agencies publish, which typically means new model-year rows appear in the autumn and crash-test results follow through the model year as vehicles are tested. Because certification data is filed per configuration, treat any single headline number for this vehicle with caution: the figure that applies to a specific car depends on its engine, drivetrain, body style and model year, all of which are listed separately above. If a number here disagrees with a brochure, the brochure is usually quoting the best available configuration rather than the one being sold.

Will the BMW 3 Series fit your garage and parking space?

Measured against a standard single garage door (8 ft wide, 7 ft tall, 20 ft deep stall) and a standard US surface parking space (9 ft x 18 ft). Measure your own opening before buying — older garages are frequently narrower.

Garage door width

Fits

72 in wide (body only, mirrors folded) — about 24 in of total clearance, so roughly 12 in per side.

Garage door height

Clears

59.4 in tall — 24.6 in of headroom before roof rails, antennas, or a roof box are added.

Parking space

Fits a standard stall

190.2 in long leaves 25.8 in to spare in an 18 ft space, and 36 in of side clearance in a 9 ft one.

Size drift: the 2026 BMW 3 Series is 3 in longer than the 2015 car in our records. If you are replacing an older example with a newer one, check the garage clearance again rather than assuming the outgoing car's footprint carries over.

Its wheelbase (112.2 in) accounts for about 61% of overall length. A higher share generally means shorter overhangs — better approach and departure clearance on driveways and ramps, and more cabin space for the same parking footprint.

Frequently Asked Questions About 3 Series Dimensions

How long is the BMW 3 Series?

The BMW 3 Series is 185.433 inches long, 72.0472 inches wide and 56.6929 inches tall. That is roughly 15.5 feet — compare it with your garage depth before buying.

Will the BMW 3 Series fit in a standard garage?

A standard single-car garage is about 20 feet (240 in) deep and 10 feet (120 in) wide. At 185.433 in long and 72.0472 in wide, the BMW 3 Series fits with 55 in of room to spare front-to-back. Remember to allow for mirrors and door swing.

How much does the BMW 3 Series weigh?

Curb weight for the BMW 3 Series is about 3,825 lbs. Curb weight excludes passengers and cargo, so add roughly 150 lbs per occupant when calculating payload.
