I learned the hard way how important it was to do research on baby car seat sizes as I couldn’t fit the first baby car seat to my Sedan.

After learning about baby car seat regulations and knowing that I’d need to get a baby car seat immediately after I deliver my newborn infant, I got a car seat without doing proper research on the car seat sizes. If you have a small car such as Toyota Corolla Sedan, you should make sure you’re getting a car seat that measures 16″ Wide or lower. They are a few car seats of such sizes and we’ve ranked the top car seats for any car with limited rear and front-seat space.

Measurements of Rear and Front Spaces of Small Cars

Below is an image of the Honda Civic, one of the most popular small cars on the market

Honda Civic

The Honda Civic above is similar to several Sedans such as Honda Fit, Honda Odyssey, Audi, Toyota Corolla, among others. Their space at the back and at the front is not as big and they score poorly on safety. Here is a scorecard for Honda Civic:

Use Backseat Dimensions of your small cars to narrow your list of most suitable car seat brands;

Rear shoulder room:

The Rear Shoulder Room which is the measurement from one door panel to another on the interior usually ranges from 49 to 68 inches. For example, Toyota Corolla has rear shoulder room of 51.7 inches, hip room of 51.3 inches and legroom of 34.8 inches. These measurement would be found in the car’s technical specification under ‘passenger volume’ or ‘interior dimensions.’ You can also find this information on the website of the car dealership or on the website of the car manufacturer.

The average amount of space in the backseat of a small car is about 53 inches. This number will give you a rough idea of how much space is available in the backseat, but it’s important to keep in mind that there can be significant variation from one small car to another. For example, the Honda Civic has significantly more rear legroom than the Toyota Corolla.

Rear hip room:

Rear hip room usually ranges from 42 – 66 inches. IN smaller cars, such as the Honda Fit, rear hip room can be as low as 42 inches. In larger cars, such as the Toyota RAV4, rear hip room can be up to 66 inches.

Rear legroom:

Rear legroom usually ranges from 29 – 45 inches. In smaller cars, such as the Fiat 500,Ford Focus, Toyota Taxoma, rear legroom can be as low as 29 inches. In larger cars, such as the Honda CR-V, Hyundai Tucson, Subaru Outback, rear legroom can be up to 45 inches.


The width of a car’s backseat also varies significantly from one model to another. The width of the backseat is typically between 36 and 40 inches. However, there are some models that have backseats that are significantly wider. For example, the Audi A3 has a backseat that is 44 inches wide.


The height of the backseat also varies from one car to another. The height of the backseat is typically between 28 and 34 inches. However, there are some models that have backseats that are significantly taller. For example, the Honda Crosstour has a backseat that is 38 inches tall.

Space in the trunk

The amount of space in the trunk or cargo area also varies from one small car to another. The trunk or cargo area is typically between 10 and 14 cubic feet. However, there are some models that have trunks or cargo areas that are significantly larger. For example, the Audi A3 has a trunk that is 14.1 cubic feet.

The average small car has about 36 inches of headroom in the front and about 35 inches of headroom in the rear. However, there can be significant variation from one model to another. For example, the Fiat 500 has 37 inches of headroom in the front and 36 inches of headroom in the rear.

The average small car has about 41 inches of legroom in the front and about 34 inches of legroom in the rear. However, there can be significant variation from one model to another. For example, the Honda Civic has 42 inches of legroom in the front and 37 inches of legroom in the rear.

The average small car has about 54 inches of shoulder room in the front and about 53 inches of shoulder room in the rear.

Dimensions of My favorite pick in this list of best car seat for small vehicles

The average backseat dimensions in small cars are about 14 inches wide and 26 inches long.

Factors to Consider when Choosing the Perfect Car Seat for a Small Car:

To pick the best car seats for small cars, it is important to understand how these dimensions are applicable when finding the ideal-size car seat.

Besides the obvious factor of a car seat fitting into the backseat, other important considerations are how much room is available for the front passenger and whether there is enough space for the car seat to recline.

The following list provides information about finding car seats that fit well in small cars by taking into account both of these aspects:

  1. Look for a “narrow” car seat. These are designed to fit well in small cars while still providing enough space for the front passenger. Go for brands with a width of 17 inches or less.
  2. Look for a car seat with a “rear-facing only” option. This will give you more space in the front seat and still provide a safe and comfortable ride for your child.
  3. Choose a car seat with a “no-recline” feature. This will allow you to maximize the amount of space in the front seat and still keep your child safe and comfortable.
  4. If you have a small car with limited space, consider using a “booster seat” instead of a traditional car seat. This will give you the ability to safely transport your child while still having plenty of room in the front seat for the driver.
  5. Measure the dimensions of your car’s backseat before you go shopping for a car seat. This will ensure that you get the right size seat for your vehicle. If your car has rear-seat dimensions such as 14 inches wide and 26 inches long, then you will need to find a car seat that is within these dimensions.
  6. Don’t forget to take into account the positioning of the front seats when measuring the backseat. If the front seats are positioned close to the dash or center console, then you will need to find a car seat with a “narrow” width in order to maximize the amount of space in the backseat.

Other Things to consider when purchasing a car seat for a small car:

  • Weight and height limits
  • Stroller compatibility
  • Front to backspace
  • Installation
  • Ease of removal
  • Safety rating

Our Reviews of Best Infant Car Seat for Small Cars:

Chicco Keyfit 30:

  • Dimensions(L/D,W,H): 27.5 x 16.75 x 24 inches

Multiple reviewers report the dimensions and shape of this seat were key to fitting three car seats in a row. At 27.5 inches deep, it’s one of the slimmest seats on the market, making it a good choice for small cars. Compared to Cybex Anton 2 above, it’s 2.5 inches deeper in depth, but only half an inch wider in width.

The width and height of the Chicco Keyfit 30 are nearly identical to the Graco Extend2Fit, except that the Chicco Keyfit is slightly shallower in depth by 3/4 of an inch. This may not seem like much, but it can make a big difference when fitting three car seats across the backseat of a small car.

In addition, Chicco’s SuperCinch Force-Multiplying LATCH Tightener helps achieve a secure fit with a fraction of the effort. The Chicco Keyfit 30 also comes with a built-in lock-off for installing the seat without LATCH, making it easier to install in a rental car or other vehicle where LATCH is not available.

Chicco KeyFit seat also comes with a removable head and body support for your newborn and a canopy. Additionally, it has a SuperClinch tool that helps you to tighten the LATCH straps during installation. It is also compatible with Chicco strollers making it a great traveling asset.


  • It is 17 inches wide occupying only small space
  • Weight/height limit of 30 pounds/30 inches tall
  • Canopy
  • SuperClinch tool
  • Adjustable straps
  • Recline Sure spring level footing and RideRight bubble indicators
  • Smooth underside


  • Compatible with Chicco strollers
  • Removable newborn head and body support for added comfort and security
  • Recline Sure spring-loaded level foot and RideRight bubble level indicator to guide your installation process
  • Smooth underside ensuring your car is protected


  • It is a little expensive
  • Although it is a convertible seat, you will need to buy a back booster eventually
  • Cumbersome to move between cars
  • Because it is a bit slimmer, it may be hard to fit multiple NextFit Zips in some back seats.

Baby Trend EZ Flex Loc Infant Car Seat

  • ‎Dimensions(L/D,W,H): 16.25 x 14.66 x 26 inches

For almost a third of the cost of the Chicco Keyfit30 above, this inexpensive Baby Trend model has the best depth suitable for small vehicles – just 16.25 inches or about 0.25 inches above my sweet depth dimension of 16 inches. While this model is at par with Keyfit30 in terms of weight, this model has narrower width, about 2.09 inches narrower.

Reviewers also say that it’s easy to install, and the harness is adjustable from the front, making it easier to get a snug fit.

Baby Trend Ex-Loc Infant car seat came second on this list and we added to it here specifically because of its affordability. Aside from its affordability, you’ll really like the sleek design of this infant car seat and it is very easy to install with two options – LATCH and belt installation.

Baby Trend EZ Flex Loc is a great option for a cheaper bucket-style infant seat for a small car. It is suitable for Toyota Corolla, Honda Civic, or any sedan. The seat is very compact and one of the narrowest rear-facing car seats in the market. It is, however, lacking in comfort with a lack of thick padding and softer fabric but considering that it costs less than $100, you’re getting real value for your money getting this seat.

Besides, this infant car seat is among the safest with a 5-point safety harness, easy one-hand harness adjustment, and push-button release. It also has eps energy-absorbing foam for superior side impact head protection.

This seat also fits 3-across as described by a user below;

Best Convertible Car Seat for Small Cars

Graco Extend2fit:

  • Dimensions (L/D,W,H)‎: 21.5 x 19.5 x 23.5 inches

Our overall best convertible car seat for small cars such as sedans and hatchbacks is the Graco Extend2Fit which has a long lifespan lasting for up to 10 years!

If you want a convertible car seat that can still grow with your baby and fit in compact space in small cars, Graco’s brand called the Graco Extendfit is your best option. Despite it being 5.5 inches deeper than our preferred 16-inch depth for sedans and small SUVs, there is no other brand with better ratings and a more perfect fit to install on your car than this brand.

This car seat is the perfect solution for many small vehicles, thanks to its shortened height of 23.5 inches and depth/length of 21.5 inches. Compared to Chicco Keyfit 30 above, it’s just half an inch shorter in height, but 6 inches shorter in depth/length- making it a much more viable option for smaller cars.

Diono Radian 3R

  • Dimensions(L/D,W,H):‎16 x 17 x 28.5 inches

Scarymom’s list reviewing small-car car seats noted that Diono Radian 3R was designed specifically to fit three car seats neatly in one row. With 17 inches wide and a mere 16 inches deep, these slim car seats for small cars will leave you with plenty of room to spare.

Its depth is the smallest in this list and is even shallower than the Chicco Keyfit 30 by 1.5 inches. However, it’s nearly an inch wider than the Chicco Keyfit 30.

The Diono Radian 3R is also one of the tallest seats on this list, at 28.5 inches tall. This can be both a good and bad thing- it’s good because it will give your child more headroom as they grow, but it can be bad because it may not fit well in smaller cars.

You won’t have to struggle pushing the seat all the way to get more room at the back as the Diono Radian 3R has a slim design.

COmpared to our convertible seat pick in this list, Graco Extend2Fit, the Diono Radian 3R is 5.5 inches shallower in depth and 2.5 inches wider in width. While this may not seem like much, it can really make a big difference when fitting three car seats across the backseat of a small car.

Diono Radian RXT Convertible Car Seat

With a depth of 17 inches, this RXT model by Diono is 1 inch deeper than the Diono Radian 3R. 3R model, however, is wider by 1 inch but both models are considered excellent for tiny vehicles.

Additionally, this convertible seat is easy to transport by carrying it on your back, something you don’t get with most convertible seats. Diono RXT also comes with a steel frame and rear-facing top tether, which keeps the seat from moving in the event of an accident. It is also an excellent option for a twin car seat.


  • It is 17 inches long X 28.5 inches high X 16 inches wide
  • Accommodates from birth to 120 lbs.
  • Weighs 27 pounds
  • Steel frame and rear-facing top harness for enhanced safety

  • Excellent compact all-in-one option

  • Pricier in comparison

Cyber Aton 2:

  • Dimensions(L/D,W,H): 25. inches x 17.25 inches x 12.25 inches

While a little wider than the Chicco Keyfit 30 (half an inch), the Cybex Aton 2 is 2.5 inches shallower in depth. Compared to Chicco Keyfit 30 above and Graco ExtendFit above, it’s just 2 inches shorter in height, but 4.5 and 5.5 inches shorter in depth/length, respectively.

Compared to Graco Extend2Fit above, it’s just 1.5 inches shorter in height, but 2 inches shorter in depth/length- making it a more viable option for smaller cars.

Best Small-car Booster car seat:

Peg Perego Viaggio Flex 120

  • Dimensions(L/D,W,H): 22″ x 17.25″ x 26.75″

If you want a booster seat instead, the Peg Perego Viaggio Flex 120 is one of the best car seats for small cars. It’s a bit deeper than most (22 inches) in this list, but it’s still slim at 17.25 inches wide and 26.75 inches tall, making it easy to fit three across. Compared to Chicco Keyfit 30 above, it’s 4.5 inches deeper, but only an inch wider in width. However, it is 6 inches taller in height. Compared to Diono Radian 3R above, it’s 5.5 inches deeper in depth and 5 inches wider in width, but 6 inches shorter in height.
