How to Choose a Double Stroller Side by Side | Width Matters Most

Choose a side-by-side double stroller by first measuring your doorways and trunk, then comparing seat limits and safety features.

Choosing how to choose a double stroller side by side starts with one number: the width. Side-by-side doubles place both seats next to each other, giving each child equal views and similar seating. The tradeoff is that they run wide, and a stroller that clears your front door but sticks in the nursery doorway becomes a daily headache.

Most good side-by-side models stay under roughly 30 inches wide. Anything past about 32 inches may not clear standard doorways. Before you compare fabrics or fold mechanisms, grab a tape measure and check your narrowest doorway, hallway, elevator, store aisle, and car trunk opening. That single step eliminates half the models on the market.

What To Measure Before You Shop

Doorway clearance is the deciding factor for side-by-side strollers. Even a two-inch difference changes which models fit your home. Write down these numbers before you shop: the width of your narrowest interior door, the front door, any elevator or hallway you use daily, and the trunk opening of your car with the stroller’s folded dimensions in mind.

Do not assume the stroller folds compactly in double mode. Some models fold easily as singles but become awkward with both seats attached. Check the folded dimensions with both seats in place, not just the marketing photos of a tidy single-seat fold. Those photos routinely hide storage fit problems.

Seat Limits: Are Both Seats Newborn-Ready?

Confirm each seat’s minimum age and weight requirements. Some side-by-side doubles are not from-birth on both seats, so verify before you buy rather than assuming. Children often hit the height limit before the weight limit, so compare per-seat maximums for both.

Independent recline matters more than you might expect. Look for both seats to recline separately so one child can nap while the other sits upright. Check the harness system too — each seat should have a genuine five-point harness, not a lap belt in disguise.

If you plan to use infant car seats, confirm whether the stroller accepts them natively or requires sold-separately adapters. That add-on cost changes your real total. The same logic applies to bumper bars and second-seat purchases. Do not rely on headline pricing alone; some double strollers need extra purchases before they work for your children.

Safety Standards And Real-World Handling

For a U.S. audience, look for compliance with ASTM F833, the current voluntary consumer safety specification incorporated into the federal stroller rule 16 CFR Part 1227 enforced by the CPSC. A JPMA certification seal is an ideal extra, since it signals independent third-party testing on top of the baseline standard.

Inspect the practical safety details: a reliable parking brake, locked hinges, and no pinch points where small fingers can reach. Avoid hanging heavy bags from the handlebar — it changes the stroller’s center of gravity and can tip it backward. Check the stroller’s stated storage and load limits and stay within them.

Side-by-side strollers generally steer more easily than tandem models because the weight sits balanced between the two wheels. The tradeoff is width. They handle well outdoors but feel bulky in narrow indoor spaces, so match the stroller to your actual environment, not just the one you want.

Once you have narrowed your list by width and seat limits, compare the models that pass those tests side by side. Our tested roundup of the best double stroller side by side options walks through real-world performance on each of these points.

Checkpoint What To Look For Why It Matters
Stroller width Under 30 inches; measure doorways first Models wider than 32 inches may not clear standard doors
Seat limits Minimum age and maximum height per seat Children often outgrow height limits before weight limits
Newborn readiness From-birth support or infant car seat acceptance Not all side-by-side doubles work for both seats from birth
Recline Independent recline on both seats Lets one child nap while the other sits upright
Harness Five-point harness on each seat Keeps an active toddler securely contained
Safety compliance ASTM F833 and ideally JPMA seal Meets the U.S. federal standard in 16 CFR Part 1227
Folded size Measured with both seats attached Some strollers fold easily as singles but not as doubles

What Most Buyers Miss

Buying guides from Choice, Consumer Reports, and BabyGearLab consistently flag the same oversight: shoppers compare prices and colors before measuring their own spaces. Doorway fit and trunk clearance are the boring details that determine whether a stroller works for you daily. Choice’s double stroller buying guide makes the same point about measuring first.

Also check the brake quality in person if you can. A parking brake that engages with one step and holds firmly on a slope is worth more than any fabric upgrade. Test the fold mechanism with both seats attached, and confirm the recline adjusters are easy to reach when the stroller is fully loaded.

FAQs

Are side-by-side strollers harder to push than tandems?

Side-by-side strollers generally steer more easily than tandem models because the weight distributes evenly between the wheels. The real challenge is width, not pushing effort. They handle outdoor terrain well but feel bulky in narrow indoor spaces like store aisles and small elevators.

Will a side-by-side double fit through a standard door?

Many will not. Standard interior doors measure roughly 30 inches wide, and side-by-side strollers often run 28 to 32 inches wide. Models under about 30 inches usually clear standard doors, while anything wider may not. Measure your own doorways before ordering rather than relying on the stroller’s stated width.

Can you use a side-by-side double from birth?

Only if both seats explicitly support newborn use or accept infant car seats. Do not assume all side-by-side doubles work from birth on both seats. Check the per-seat minimum age and weight requirements on the manufacturer’s spec sheet before buying.
