"Hold the Door"
Game of Thrones Season 6, Episode 5: Bran wargs into past-Hodor while present-Hodor holds a door against an army of wights so the others can escape. The phrase "Hold the door" gets compressed across time into "Hodor" โ his only word. We knew it would end badly. We didn't know it would gut us.
This calculator estimates how long Hodor could realistically have held that door, given the door material and the attacking force.
How to Use This Calculator
Door material. Solid oak (typical castle door) is rated for ~3500 lbs of static force. Pine: ~1200. Iron-banded oak (the show's best guess): ~6000.
Attackers. Each wight pushes ~80 lbs of impact force. Default 25.
Hodor's counter-force. Default 350 lbs (his mass) plus 200 lbs braced shoulder push = 550 total.
The Formula
net force on door = (attackers ร force per wight) โ Hodor counter
seconds to failure = door rating / max(0, net force) ร scale factor
A solid oak door (3500 lb rating) facing 25 wights (2000 lb push) minus Hodor's 550 lb counter = 1450 lb net force. With a typical scale factor of ~6 seconds per lb-rating ratio, that's about 14.5 minutes before the door splinters.
Frequently Asked Questions
How long did Hodor actually hold the door on screen?
The on-screen sequence is about 90 seconds. The narrative implies he held until the door was fully splintered โ likely several minutes.
Could a real human hold a door against 25 attackers?
Probably 2โ5 minutes against an unarmed mob with no weapons. Seconds against an armed force. Hodor's a special case.
Why does Bran do this to him?
He's a teenager with godlike powers and questionable judgment. We've all been there.
Should I use this calculator on prom night?
Whatever helps you process Season 6.
How accurate is the "3,500 lb rating for solid oak" figure?
Loosely. The number is drawn from approximate static-impact ratings for thick (3+ inch) oak panel doors of the type used in castle-keep entries โ not from a precise material-engineering certification. Real medieval doors varied enormously in construction (single-panel, banded, layered with iron strapping, etc.), and the show's prop department clearly built something heavier than a typical interior door. Treat the rating as a rough envelope, not a measured value.
Why does each wight contribute 80 lbs of push?
Because the calculator approximates a wight as a body-weight-class adult pushing forward against a door. Eighty lbs is the average sustained push force a typical adult can generate against a vertical barrier without bracing โ meaningfully less than a peak shove, which can momentarily exceed 200 lbs but isn't sustainable. The calculator uses the sustained figure because the door is failing under cumulative pressure, not a single impact.
What's the scale factor of "6 seconds per lb-rating ratio" doing?
It's converting a structural-engineering force ratio into elapsed time. Doors don't fail instantaneously when net force exceeds their static rating; they fail after sustained loading concentrates damage at hinges, panels, and locking points. The 6-second-per-unit factor is a rough conversion calibrated against the on-screen 90-second visible sequence plus the narrative implication that the door held meaningfully longer off-screen.
Could Hodor's counter-force be higher with proper bracing?
Yes. A 350-lb person with their back against the door, feet braced against the opposite wall, and a wedge under the bottom edge can sometimes resist forces in excess of their own body weight by a factor of 2โ3x. The default 550 lbs is conservative; if you wanted to model a fully braced, leveraged Hodor with limited room behind him, you could bump that figure to 900โ1100 lbs and stretch the time-to-failure significantly.
Does the calculator account for the door being unbarred?
The on-screen door is shown without a heavy crossbar (which would have changed everything), only Hodor's body. The calculator implicitly assumes the door is unbarred โ Hodor is the load-bearing element. If you want to model a properly barred door, you could simply zero the attacker_force input or set Hodor's counter to a much higher figure to represent the bar's contribution.
A Worked Example
You're modeling a thinner pine door (rating ~1,200 lb) against only 12 attackers, but Hodor is fresh and well-braced (counter-force 700 lbs).
Half a minute before the pine fails. Same setup with an iron-banded oak (6,000-lb rating): the door holds for about 2 minutes 18 seconds. Add another 10 wights (22 total), and the pine door fails in under 6 seconds while the iron-banded oak still buys nearly a minute.
The biggest single variable is the door, not Hodor. He buys you incremental time; the door buys you the order of magnitude.
Behind the Numbers
"The Door" (Season 6, Episode 5, May 2016) is widely regarded as one of Game of Thrones' emotional high points. The episode's writers, David Benioff and D.B. Weiss, have noted that George R.R. Martin gave them the reveal โ that "Hodor" was a compression of "hold the door" warged across time โ years before the show needed it. The scene's structural math wasn't the priority; the time-loop reveal was.
The figures used here aren't engineering-grade. Real castle-door failure analysis is a niche field, and the data we have on medieval door construction is more historical than physical. The calculator's goal isn't to be a structural engineering tool; it's to give a rough, defensible estimate that makes the scene's implied timeline plausible. By the math, a solid oak door against a typical wight column with Hodor braced holds for several minutes โ long enough for the show's narrative purposes. That's the only check the calculator was built to pass.
