Are you focusing on the wrong number when choosing a car?

\n\n

\n \n

Check overall length against your garage before you buy.

\n \n\n

You’ve probably glanced at a spec sheet, seen “overall length” and thought, longer equals bigger equals better. Then you meet the garage. One Auckland reader told me how their shiny midsize sedan scraped by the roller door with centimetres to spare and left no room for the pram. In Sydney’s inner west, a mate learned the hard way that his big SUV fit the driveway but couldn’t swing into the apartment’s tight basement bay without a three‑point shuffle, every single day.

\n\n

Here’s the twist: length matters a lot for parking, but it’s not the magic key to comfort or manoeuvrability. In fact, misreading length is one of the fastest paths to buyer’s remorse. The good news? A small set of measurements and a quick bit of maths can prevent all of it.

\n\n

What does “length” actually measure and how do you convert it?

\n\n

Manufacturers publish “overall length” as a bumper‑to‑bumper number. That’s the one to use when checking fit. Example: a 2024 Toyota Camry lists around 4,885 mm overall length (192.1 in) in Australian spec sheets (carsguide.com.au).

\n\n

1 mm = 0.03937 in. 1,000 mm ≈ 3.281 ft.
4,500 mm ≈ 177 in ≈ 14.8 ft; 5,300 mm ≈ 209 in ≈ 17.4 ft.

\n\n

Reframe how you judge “size”: start with spaces, not the car

\n\n

The most common mistake is assuming exterior length equals interior comfort and that longer is automatically more practical. Not quite. Wheelbase and packaging drive legroom; turning circle drives city manoeuvrability; and the spaces you use daily dictate whether living with the car is relaxed or frustrating.

\n\n

Think of your car as a suitcase. Overall length is the outside dimension; wheelbase is how that length gets divided inside your “case.” Long overhangs are like decorative trim - they change how the suitcase looks and how it fits in the overhead bin, but not how much you can pack.

\n\n

Better questions to ask yourself:

Where do I park every day and how long are those spaces in millimetres?
What’s my minimum turning circle tolerance for my driveway and local streets?
How much front/rear and side clearance do I need to load kids, bikes, or the weekly shop?

\n\n

Will it fit where you actually park?

\n\n

Here’s the practical, slightly uncomfortable truth about fit:

Common off‑street bay sizes: many Australian and NZ car parks use bays around 2.4-2.7 m wide by 5.4-5.5 m long. In US municipal standards, 9 × 18 ft (≈ 2.7 × 5.5 m) is a staple reference (ecode360.com). If your car is 5,300+ mm long, you’ll use almost all of that depth.
Parallel parking: practical design lengths often run 6.1-6.7 m (20-22 ft) to allow for manoeuvring (parkmodo.com). If you rely on on‑street parking in suburbs with tight kerb spaces, every extra 100 mm matters.
Overhang allowance: many lot designs assume 300-600 mm bumper overhang beyond a line when there’s a kerb or landscape strip (see FHWA planning norms). If there’s a wall, assume no overhang.
City lanes and aisles: Negotiating tight aisles into a perpendicular bay depends on your car’s turning circle and projection. Longer vehicles need wider aisles to swing in cleanly (ecode360.com).

\n\n

\n \n

Some bays leave almost no margin for long vehicles.

\n \n\n

Unexpected but crucial:

Two cars of the same overall length can behave very differently in tight turns due to wheelbase and steering geometry. Rear‑wheel steering on some models effectively tightens the turning circle.
A long front or rear overhang can worsen approach to ramps or kerbs even when the wheelbase is modest.

\n\n

Does a longer car really mean more space inside?

\n\n

Not automatically. Wheelbase - the distance between front and rear axles - correlates more strongly with legroom than overall length. Packaging choices, seat rail design, and body shape matter too.

\n\n

Short overhangs with a decent wheelbase can yield generous cabins without a huge footprint. Many boxier SUVs deliver better cargo utility than sleeker sedans at the same length thanks to their shape (see Honda CR‑V load space vs. overall length in MotorTrend specs).
Some designs grow length for styling or crash structures rather than cabin space. That looks sharp at the kerb, but it doesn’t help prams or pets.

\n\n

The stakes: a quick reality check

Time cost: wrestling a too‑long car into a tight bay adds minutes and stress daily. Over a three‑year lease, that’s dozens of hours lost.
Money cost: door dings, scraped bumpers, and parking tickets for overhangs or misaligned parks add up fast.
Comfort cost: misjudged legroom and cargo height/shape lead to awkward family trips, sore backs loading child seats, and the uncanny feeling your “big” car isn’t actually roomy.

\n\n

A short story you might recognise: Ana in Wellington bought a midsize sedan thinking it’d be perfect for her newborn twins. It fit in the 5.5 m apartment bay, just. But the pram wouldn’t clear the wall behind the car, and she had to reverse out to buckle the capsules on wet, windy days. When she swapped to a slightly shorter but boxier compact SUV, daily life got easier even though the SUV wasn’t longer.

\n\n

Which numbers matter when you’re narrowing choices?

\n\n

Bring a new lens to your shortlist. Prioritise:

Overall length vs. your spaces: Compare your car’s exact published length to your garage and typical bays (carsguide.com.au lists accurate numbers).
Wheelbase and cabin measurements: Check rear legroom and cargo dimensions alongside wheelbase (carexpert.com.au for model specs like Camry/Corolla).
Turning circle: For inner suburbs, look closely at turning circle diameter in metres. It’s the most useful single metric for low‑speed manoeuvrability.
Body shape: Hatch/crossover bodies often give better cargo use at the same length than sedans.

\n\n

How long is a “typical” car? Quick ranges with examples

Micro/city cars: ~3,500-3,800 mm. Example: Mini Cooper ≈ 3,866 mm (motordonkey.com).
Small/supermini hatch: ~3,800-4,200 mm.
Compact hatch (C‑segment): ~4,200-4,400 mm. Example: VW Golf Mk7 ≈ 4,255 mm (Wikipedia).
Compact sedans: ~4,300-4,600 mm. Example: Toyota Corolla range ≈ 4,375-4,630 mm (carsguide.com.au).
Midsize sedans: ~4,600-4,900 mm. Example: Camry ≈ 4,885 mm (carsguide.com.au).
Compact SUVs: ~4,400-4,700 mm. Example: Honda CR‑V ≈ 4,695 mm (MotorTrend).
Large SUVs: ~5,000-5,700+ mm. Example: Chevrolet Tahoe ≈ 5,350-5,370 mm depending on trim.

\n\n

How do you right‑size a car to your garage and routine?

\n\n

Use the PARK-IT framework to make the decision simple:

\n\n

P Parking spaces: Measure your garage internal length and width (use smallest clear dimension), plus your common off‑street and on‑street space lengths.
A Agility: Note turning circle (m) and consider rear‑wheel steering options if you often tackle tight ramps or cul‑de‑sacs.
R Room: Check wheelbase, rear legroom, and cargo volume/shape; don’t assume length equals space.
K Keep‑clear: Aim for 300-600 mm clearance front and rear in your garage, and 450-900 mm each side for doors and walking space.
I Inches/mm: Convert the car’s published mm to ft/in if it helps visualise. Example: 5,000 mm ≈ 16.4 ft.
T Test‑turn: On a test drive, park it in a tight spot like the one you’ll actually use. Don’t just loop the block.

\n\n

Practical steps that work in AU/NZ homes

\n\n

\n Measure twice\n
- Internal garage length: wall to inner face of the door; note any shelving, steps, or a door closer that steals space.
- Internal width: wall to wall at mirror height. Mirrors can add 150-200 mm per side.
\n
\n Do the quick maths\n
Required garage length ≈ car length + front clearance + rear clearance.
\n
Example: 4,885 mm Camry + 500 mm front + 500 mm rear = 5,885 mm required inside (≈ 19.3 ft).
\n
Required width ≈ width including mirrors + side clearances. Example: 2,050 mm with mirrors + 450 mm each side ≈ 3, -950 mm.
\n
\n Compare with your daily parks\n
If your office bay is 5,400 mm long and your SUV is 5,300 mm, you’ve got a 100 mm margin before touching the wall. That’s razor thin. Look for shorter overall length or more forgiving spaces.
\n
Parallel park often? Target cars comfortably under your typical curb length; 20-22 ft kerb lengths (≈ 6.1-6.7 m) are common planning numbers (parkmodo.com).
\n
\n Think about doors and life admin\n
- Child seats need more side clearance. Plan 600-900 mm per side.
- If you fold mirrors to squeeze in, remember that reduces width, not length.
\n
\n Consider manoeuvrability tech\n
Rear‑wheel steering can meaningfully reduce turning circle on longer vehicles; still, check the published turning circle figure to be sure.
\n

\n\n

Trade‑offs and a few hot debates

“Longer equals roomier” isn’t a rule. Wheelbase and packaging drive comfort; overhangs can add length without cabin gain.
Designers sometimes add length for styling or safety structures. Looks great, parks worse.
Tech helps, but physics still wins. A long car with clever steering may turn like a shorter one at low speed, but it still occupies more curb length and may struggle in short bays.

\n\n

Your action checklist

Measure your garage internal length/width in mm. Write it down.
List the cars you’re considering. Note: overall length (mm), wheelbase (mm), turning circle (m), width including mirrors.
Compute required garage length = car length + 300-600 mm front + 300-600 mm rear.
If required length exceeds your garage, cross it off unless you plan changes.
If you rely on street parking, use 6.1-6.7 m (20-22 ft) as a practical parallel length check for comfortable manoeuvring.
Test drive to a real‑world car park or your driveway if the dealer allows.

Examples to ground your thinking

Mini Cooper (small hatch): 3,866 mm - a dream for inner‑city bays (motordonkey.com).
VW Golf (compact hatch): ≈ 4,255 mm - compact outside, practical inside (Wikipedia).
Toyota Corolla: ≈ 4,375-4,630 mm - check hatch vs. sedan lengths (carsguide.com.au).
Toyota Camry: ≈ 4,885 mm - midsize sedan, great for families if your garage suits (carsguide.com.au).
Honda CR‑V: ≈ 4,695 mm - boxier cargo at similar length to sedans (MotorTrend).
Chevrolet Tahoe: ≈ 5,350-5,370 mm - illustrates how large SUVs interact with 5.4-5.5 m bays.

\n\n

Bottom line

Overall length is your gatekeeper for parking fit, but wheelbase, turning circle, and body shape decide how easy the car is to live with. Measure your spaces, add comfortable clearance, and check the right specs before you fall in love on the forecourt.

A car that fits your life - not just your driveway - will keep paying you back every single day.
