BMW 1 Series dimensions

Discover the height, width, length, boot space and more of BMW’s popular hatchback

Getting to know the BMW 1 Series dimensions is an important part of deciding if this is the car for you.

It’s a premium hatchback that’s deceptively spacious, so it can be a decent option for a posh family car.

What are the dimensions of the BMW 1 Series?

The 2020 BMW 1 Series model has slightly different dimensions than some of the earlier editions.

It’s 34mm wider and 13mm taller than the 2017 BMW 1 Series, and 5mm shorter, but you probably won’t even notice from the driver’s seat.

The BMW 1 Series is pretty spacious inside. You do get slightly more headroom in the front (1,019mm) because of the sporty, sloping roofline, though.

Headroom in the rear sits at 956mm, so it’s still roomy enough.

The width in the rear of the cabin is slightly wider at 1,430mm, compared to 1,442mm in the front.

Changes in interior dimensions between the current and previous-gen 1 Series are as near as makes no difference.

There’re five seats across all models and ISOFIX car seat points if you need to safely fit a child seat.

The BMW 1 Series boot dimensions will be important if you’ve got plenty to pack up and travel with.

The standard boot size for the BMW 1 Series is 380 litres, going up to 1200 litres if you fold down the rear seats.

This is enough for a pushchair or a couple of suitcases, and you can fit that all in together if you flatten the rear seats.

Keep in mind that the rear seats fold down in a 60:40 split in older generations but have a 40:20:40 split in the 2024 model.

As you can see, the BMW 1 Series dimensions are super practical and one of many reasons it remains a popular hatchback.

Passengers in the front and the back will be comfy, just as long as you don’t squeeze three adults into the rear seats.

And the boot is ample for daily use and won’t leave you stressed after a reasonable flatpack furniture shopping trip.
