Magic Kingdom currently has seven rides with minimum height requirements, ranging from 32 inches for Tomorrowland Speedway to 48 inches for TRON Lightcycle / Run. Most other Magic Kingdom rides have no minimum height requirement.
If you’re visiting with children close to one of the cutoffs, I would check the height requirement before building your day around the ride. Disney measures guests at the attraction, and the Cast Member’s measurement at the park is what ultimately matters.
Magic Kingdom Height Requirements Chart
| Ride | Minimum Height | Centimeters |
|---|---|---|
| Tomorrowland Speedway | 32 in | 81 cm |
| The Barnstormer | 35 in | 89 cm |
| Big Thunder Mountain Railroad | 38 in | 97 cm |
| Seven Dwarfs Mine Train | 38 in | 97 cm |
| Tiana’s Bayou Adventure | 40 in | 102 cm |
| Space Mountain | 44 in | 112 cm |
| TRON Lightcycle / Run | 48 in | 122 cm |
Disney can change attraction requirements, so I also check the official Magic Kingdom attraction list before a trip.
Magic Kingdom Rides by Height
If you’re planning around a child’s height rather than a specific attraction, this is the easiest way to look at the requirements.
32 Inches
- Tomorrowland Speedway: 32 inches / 81 cm
Tomorrowland Speedway has one additional rule: guests must be at least 54 inches / 137 cm to drive alone. A guest who is at least 32 inches tall can ride and drive when accompanied by someone who is at least 54 inches tall.
35 Inches
- The Barnstormer: 35 inches / 89 cm
The Barnstormer is the lowest-height roller coaster at Magic Kingdom and can be a useful first step before the larger coasters.
38 Inches
- Big Thunder Mountain Railroad: 38 inches / 97 cm
- Seven Dwarfs Mine Train: 38 inches / 97 cm
Big Thunder and Seven Dwarfs currently share the same minimum height requirement.
Big Thunder’s current 38-inch minimum is especially worth checking against older planning information, because older Disney guides listed a higher requirement before its major refurbishment.
40 Inches
- Tiana’s Bayou Adventure: 40 inches / 102 cm
Tiana’s Bayou Adventure includes a large final drop, so meeting the height minimum doesn’t necessarily mean every child will want to ride.
44 Inches
- Space Mountain: 44 inches / 112 cm
Space Mountain is an indoor roller coaster ridden largely in darkness, which can make it feel more intense than the height requirement alone suggests.
48 Inches
- TRON Lightcycle / Run: 48 inches / 122 cm
TRON has the tallest minimum height requirement of any current Magic Kingdom ride.
If you’re comparing the intensity of the restricted rides rather than just their height minimums, see my Magic Kingdom thrill rides guide.
Which Magic Kingdom Rides Have No Height Requirement?
Most Magic Kingdom attractions have no minimum height requirement. That includes many of the park’s classic family rides.
- Astro Orbiter
- Buzz Lightyear’s Space Ranger Spin
- Dumbo the Flying Elephant
- Haunted Mansion
- “it’s a small world”
- Jungle Cruise
- Mad Tea Party
- The Magic Carpets of Aladdin
- The Many Adventures of Winnie the Pooh
- Peter Pan’s Flight
- Pirates of the Caribbean
- Prince Charming Regal Carrousel
- Tomorrowland Transit Authority PeopleMover
- Under the Sea – Journey of The Little Mermaid
“Any height” does not mean every attraction is identical for infants, toddlers or nervous children. Ride vehicles, seating, darkness, drops and other attraction characteristics still matter.
If you’re specifically planning for very young children, my Magic Kingdom rides for toddlers guide is more useful than choosing solely by height requirement.
Can a Child Ride If They’re Just Under the Height Requirement?
No. Minimum attraction heights are safety requirements, and riding with an adult does not override them.
If a child is close to the cutoff, use the measuring marker at the attraction entrance. Cast Members may also measure again later in the queue before boarding.
I would avoid promising a borderline child that they will definitely be allowed to ride based on a measurement taken at home. The park measurement is the one that matters.
Does Disney Measure Kids With Shoes On?
Guests normally visit attractions wearing their regular footwear, but I would not try to use unusually thick or altered shoes to get around a height requirement.
Height requirements exist for rider safety. If someone is genuinely right at the minimum, let the Cast Member measure them at the attraction rather than trying to gain extra height.
What Is Rider Switch?
If someone in your party cannot or does not want to ride, Disney’s Rider Switch service can keep the rest of the group from having to wait through the full standby queue twice.
Disney currently has your entire group speak with a Cast Member at the attraction entrance. The group is then divided into two parties. One party rides first while the other waits with the non-rider, and eligible members of the second party return afterward through the designated Rider Switch entrance.
Disney says Rider Switch is available at most attractions and can be used when a guest does not meet the boarding requirements or cannot ride and cannot wait outside the queue alone.
That is much easier than trying to build separate adult and child itineraries around every height-restricted attraction.
Which Magic Kingdom Ride Has the Highest Height Requirement?
TRON Lightcycle / Run has the highest minimum height requirement at Magic Kingdom at 48 inches / 122 cm.
Space Mountain is next at 44 inches, followed by Tiana’s Bayou Adventure at 40 inches.
Which Magic Kingdom Coaster Has the Lowest Height Requirement?
The Barnstormer has the lowest coaster height requirement at Magic Kingdom at 35 inches / 89 cm.
Big Thunder Mountain Railroad and Seven Dwarfs Mine Train both currently require 38 inches.
If you’re specifically comparing every coaster, see my Magic Kingdom roller coasters guide.
The Height Requirements I Would Save on My Phone
If you only want the quick reference, remember these numbers:
- 32 inches: Tomorrowland Speedway
- 35 inches: The Barnstormer
- 38 inches: Big Thunder Mountain Railroad and Seven Dwarfs Mine Train
- 40 inches: Tiana’s Bayou Adventure
- 44 inches: Space Mountain
- 48 inches: TRON Lightcycle / Run
- 54 inches: required to drive Tomorrowland Speedway alone
Everyone else can use this page as a quick filter: if the attraction isn’t one of those seven height-restricted rides, it generally falls into Disney’s any-height category.
Because these requirements can change, I would still verify any borderline ride on Disney’s official attraction page shortly before your trip.
