The listed minimums on this site
Magic Kingdom does not have one height rule. The coasters in this index sit on four different lines, and the classic dark rides often have none. That split is the whole family-planning problem — not a generic “check the park” paragraph.
4 attractions currently have a figure here. 122 cm / 48 in: TRON Lightcycle / Run. 112 cm / 44 in: Space Mountain. 102 cm / 40 in: Big Thunder Mountain Railroad. 97 cm / 38 in: Seven Dwarfs Mine Train.

How to split a mixed-height group
Measure riders the night before, in socks, against a proper mark. If someone is within a couple of centimetres of a line, assume they may be turned away and have a fallback in the same land.
- Seven Dwarfs Mine Train at 97 cm is the family coaster that queues like a headliner.
- Big Thunder Mountain Railroad at 102 cm is the outdoor mine train in Frontierland.
- Space Mountain at 112 cm is slower than people remember (about 43 km/h in the dark).
- TRON Lightcycle / Run at 122 cm is the motorcycle-style launch — the fastest coaster in this park, and a second filter even for guests who meet the number.
- Haunted Mansion has no listed minimum. Pair it with Pirates as the indoor block when coaster waits explode.
Height is not the same as “ready for TRON”
Meeting 122 cm gets you onto TRON Lightcycle / Run. It does not tell you whether you want to sit astride a motorcycle-style vehicle through a launch. Watch the POV on the ride page before you spend Lightning Lane on it.
Space Mountain is the opposite surprise: the height line is lower, the speed is modest, and the darkness does the work. Plenty of adults who enjoy TRON still skip Space Mountain because they hate indoor coasters, and plenty of families do the reverse.
