Single vs Double Stroller: How to Choose for Your Family

What defines a single and a double stroller

The U.S. Consumer Product Safety Commission (CPSC) defines a stroller as a wheeled vehicle for the transport of one or more infants or children, generally in a sitting-up or semi-reclined position, powered by a person pushing a handle. The same rule covers carriages, which are used for infants lying down. In everyday terms, a single stroller has one seat, and a double stroller has two seats. Some strollers are designed to be convertible, starting as a single and later accepting a second seat or a ride-on board.

CPSC regulations incorporate ASTM F833-21, the safety standard for carriages and strollers. This standard covers performance requirements such as parking brakes, static load, stability, and occupant retention. When you shop, look for a stroller that meets this standard, regardless of whether it is a single or double model. The standard applies to all strollers sold for use up to 36 months of age, per CPSC guidance.

Seat configurations: side-by-side and tandem

Double strollers come in two main configurations: side-by-side and tandem. Side-by-side models place the two seats next to each other, giving both children a similar view. They tend to be wider, which can make them harder to push through standard doorways. Tandem models place one seat behind the other, which makes the stroller longer but narrower. Some parents find tandem strollers easier to maneuver in tight spaces, while side-by-side models are often better for children who want to interact.

Many double strollers accept car seats with an adapter, so you can travel with a newborn and a toddler. Others offer a bench, a platform, or a second seat that clips in when needed. Convertible strollers let you start with a single seat and add a second seat later. If you think you might have a second child soon, a convertible model can save you from buying a new stroller. See our guide to single-to-double conversion for details.

When a single stroller suits your family

A single stroller is often the best choice if you have one child or if your two children are far enough apart in age that the older one can walk on his or her own. Many toddlers are able to walk short distances, but stamina varies. A single stroller lets you bring one child along while the other walks or uses a ride-on board. Ride-on boards attach to the back of a single stroller and give an older sibling a place to stand when he or she tires.

Single strollers are generally lighter, fold smaller, and fit through standard doorways more easily than double strollers. They are also easier to load into a car and to lift onto public transit. If you use your stroller mostly in urban settings or travel frequently, a single stroller might be the more practical pick. See our lightweight stroller guide for compact options.

When a double stroller suits your family

Choose a double stroller when you have two children who both need to ride. This includes twins, siblings less than two or three years apart, or any situation where one child is too young to walk and the other is not yet reliable enough to walk for long distances. Double strollers are also useful for outings where you expect long periods on foot, such as theme parks, large zoos, or all-day errands.

The age range for strollers, according to CPSC, runs from infancy to 36 months. If both of your children are under three, a double stroller is likely the right choice. But even if one child is older, a double stroller can be handy when the older child gets tired and needs a seat. Some double strollers allow one seat to be removed, effectively turning them into a single stroller for a day when only one child is along.

Double strollers are available in many styles, from all-terrain models to jogging strollers. Choose the type that matches your most common terrain and activity.

How to choose between a single and a double stroller

Start by thinking about the age gap between your children. If they are more than three years apart, a single stroller with a ride-on board may be enough. If they are close in age, a double stroller will be more useful. Also consider your lifestyle: urban parents may prefer a lightweight, narrow double stroller, while suburban parents may need a larger model with more storage. Think about your car and storage space. Double strollers are longer or wider than single ones, and they may not fit in your trunk or closet. Check the folded dimensions before buying. You can learn more in our article on stroller folded size.

Safety is paramount. Look for strollers that meet ASTM F833-21, the standard incorporated into federal regulations by the CPSC. This standard addresses brakes, stability, and restraint systems. Also, check the recall databases at SaferProducts.gov and Recalls.gov to see if a model has been reported. If you are buying secondhand, be extra careful to check that all parts are intact and that the stroller still has its manual.

What to pick for your use

Questions

Can I use a double stroller for one child?

Yes, but it will be heavier and wider than a single, and the extra seat may be wasted. Some double strollers allow you to remove a seat or use the space for storage, but stroller configurations differ in flexibility. If you only need one seat for most outings, a single stroller is often more practical.

Are double strollers safe for newborns?

Yes, if the stroller is designed to accommodate an infant car seat or has a bassinet attachment. Always follow the manufacturer's guidance and the car seat's instructions. The CPSC requires compliance with ASTM F833-21 for all strollers, which includes stability and restraint requirements.

How do I know if a double stroller will fit through doorways?

Measure the track width of the stroller (the distance between the wheels) and compare it to the width of your doorways. Standard interior doorways vary, so it's best to measure. You can also check the folded width. Our article on stroller track width explains more.

What is the difference between side-by-side and tandem double strollers?

Side-by-side models place the two seats parallel, giving each child a forward view. Tandem models place one seat behind the other, making the stroller longer but narrower. Side-by-side can be harder to fit through narrow doors, while tandem is often easier to push in tight spaces. Choose based on your doorways and how often you navigate crowded areas.

Can I convert a single stroller to a double?

Some strollers are designed to accept a second seat or a ride-on board. Check the manufacturer's specifications and whether the frame supports the extra weight. Convertible models let you start with one seat and add a second later. Our article on single-to-double conversion explains the options.

What is the maximum weight limit for a double stroller?

Weight limits vary by model and by seat. Check the manufacturer's specification for the frame and each seat. The stroller's manual lists the maximum weight for each seating position. Exceeding these limits can affect stability and safety.
