If you’re planning a trip to Disneyland or Disneyworld this summer you better check the size of your stroller.

Disney just announced that large strollers and stroller wagons are now banned from the parks. This means strollers that are “greater than 31″ (79 cm) in width and 52″ (132cm) in length” won’t be allowed into either the Florida or California Disney parks.

“These updates are designed to help guest flow and ease congestion, making the parks more enjoyable for everyone,” Lisa Mendillo, the Communications Manager for Walt Disney World Resort writes in a blog post.

Plenty of strollers (even some doubles and joggers) are small enough that they will still be allowed into Disney parks, but if you’ve got a big rig, you might want to swap if for an umbrella-style stroller before your visit, or just rent a Disney-approved stroller when you get to the park.

Here are a few popular models that fit the dimensions, according to the Disney experts at Mouse Travel Matters.

  • BOB Revolution Flex Duallie 2.0, Revolution Pro
  • Joovy Scooter x2
  • Zoe XL2 Best V2
  • Baby Jogger City Mini Double
  • Baby Jogger City Mini Double GT
  • Bumbleride Indie
  • Britax B-Agile
  • Baby Trend Expedition Double Jogger
  • Mountain Buggy Duet
  • Kolcraft Cloud Plus
  • Jeep Destination Side By Side

Bigger strollers, like the Baby Jogger Summit x3 Jogger, the Thule Urban Glide 2 Double, and the Baby Trend Navigator Double Jogger won’t fit when the Disney folks measure your rig and you’ll be turned around.

Wagons have actually been banned at the parks for awhile, but the staff haven’t always enforced the ban strictly. Starting now, they will, because with the new Star Wars: Galaxy’s Edge attraction opening in May, Disney wants to do whatever it can to minimize congestion in the parks.

Making sure the experience is fun for everyone is why the stroller rules were made, and it’s also why Disney is banning cigarette smoking from the parks as well.
