Kilter Board sizes, configs, and where to find one
Kilter Board sizes: four Original layouts from 7x10 to 16x12, the Homewall family, and how angles work. Where to climb on one, as of September 2026.
The Kilter Board is a standardised LED training wall that runs on an app. Kilter, a Colorado hold maker, launched it in 2018, and the same wall now appears in gyms worldwide. Climbers use it for repeatable training: the app lights up a problem, tracks attempts, and logs sends. This guide covers the sizes, the configs, and where to find one, as of September 2026. It sits in the site’s Training Facilities catalogue.
The Kilter Board at a glance
One board, one climb database. Every Kilter Board shares one library of problems, so a climb set in one gym works on another. That standardisation is the point: the board is the furniture, and the app is the product.
Kilter builds the system in Boulder, Colorado, where co-founders Ian Powell and Jackie Hueftle shape the holds. The company has sold about 2,100 boards, and Climbing Magazine reported roughly 8 million dollars in revenue for 2024. Setters voted Kilter their favourite board in the Climbing Business Journal’s Grip Awards from 2021 to 2024. The board is also the official training partner of World Climbing, the sport’s body formerly known as the IFSC.
The lighting system carries the climbing. Green LEDs mark the start, blue the hand holds, purple the finish, and yellow the feet only. The colour code comes from Climbing Magazine’s first look at the board. A climb’s grade is crowd-sourced. Kilter states the displayed grade is a weighted consensus, and it can move as climbers vote.
Sizes and layouts
Four Original sizes cover most gym floors. They are nested, which means the 7x10 layout sits inside the 8x12, which sits inside the 12x12, and so on. All four share the same database of climbs, per the official layouts listed by Setter Closet, Kilter’s North American dealer.
| Size (ft) | Handholds | Footholds | LEDs | Ceiling clearance |
|---|---|---|---|---|
| 16x12 | 431 | 207 | 1,300 | 12-15 ft |
| 12x12 | 323 | 153 | 1,000 | 12-15 ft |
| 8x12 | 209 | 102 | 630 | 12-15 ft |
| 7x10 | 165 | 60 | 450 | 8-11 ft |
| Per Setter Closet, as of September 2026 |
The LED count scales with the surface, which is the useful comparison when a gym advertises its board. A 16x12 board fills a large wall and needs 12 to 15 feet of clearance. The 7x10 is the smallest Original layout, carries no kickboard, and fits rooms with 8 to 11 feet of ceiling. Gym halls usually pick the 8x12 or larger, while the smaller sizes suit training rooms and homes.
The Homewall family, which Kilter calls Full Ride, shrinks the same idea for garages. It comes in 10x12, 8x12, 10x10, and 7x10, with 305 to 513 holds depending on the size. The 7x10 Full Ride kit carries 305 holds, split between a 165-hold Mainline set and a 140-hold Auxiliary set. That density is the Homewall’s signature. Climbing Magazine’s first look counted more holds on a 7x10 Kilter than an 8x12 MoonBoard with its 2019 set.
Angles: how the adjustable wall works
The frame is the second variable. Kilter Boards adjust from vertical to 70 degrees, per Gripped Magazine. The angle picker in the app works in 5-degree steps, per Kilter’s dealer Setter Closet. Forty degrees is the de facto default. The board is designed to fit under a standard ceiling at that angle, per r/bouldering.
Most gyms fix the angle rather than change it nightly. The Climbing Hangar, a UK chain, sets its boards at 50 degrees, per the chain’s own blog. One r/bouldering user described a gym board fixed at 45 degrees. Steeper angles demand more: Setter Closet’s help pages note that advanced climbers train at 45 to 60 degrees.
Climbers treat the angle as part of the difficulty. A problem impossible at 50 degrees can become fair at 40, since the hold layout stays the same. Check the angle range before you commit to a membership: the guide to gym costs compares what memberships include.
The app and the 2026 reset
The app runs everything, and in 2026 it was rebuilt from zero. On 26 March 2026 the original Kilter app disappeared without warning. Kilter announced that the third-party company operating it had taken it down, and a brand-new app launched the same day.
The reset cost climbers their logs. Old accounts did not transfer, and Kilter states that account data could not be migrated. Tens of thousands of climbers lost access to their logs overnight, per Climbing Magazine. The new app drew 20,000 downloads in its first 24 hours, then more than 35,000 within three days.
WarningOld Kilter accounts do not transfer to the new app. Create a new account, then reclaim climbs and logbooks via the claim page at kilterboard.io/claim. It accepts data exports from the former app operator.
Kilter says almost all climbs created on the old app were preserved. Users can request a data export from Aurora, the app’s former operator; uploading it reclaims climbs, logbooks, and setter credit. Grading survived the reset, and it stays crowd-sourced. Kilter’s support pages describe the displayed grade as a weighted consensus of climbers’ votes.
Where to find one
Gyms around the world carry Kilter Boards, and the app lists registered boards by gym name. A board missing from the app may simply be unregistered, per Kilter’s support pages. Asking the front desk is the reliable move.
Three verified examples show the spread: The Climbing Hangar, a UK chain, runs Kilter Boards across its venues. The chain’s blog post on the board says they are set at 50 degrees. boulderbar Wienerberg in Vienna announced its board on Instagram; in Berlin, urban apes bright site lists a Kilterboard too. The gym’s quick-overview page and the hall’s profile both document it.
Homes are the other option: the 7x10 Homewall with the Full Ride kit is the standard garage setup. It carries 305 holds, and Climbing Magazine’s 2020 first look priced it at 6,600 dollars. Owners in r/bouldering are enthusiastic. One called the 7x10 “an absolutely fantastic training tool” after six months in a garage.
- Install the Kilter app and create an account
- Check the board’s registered name in the app, or ask the front desk
- Turn on Bluetooth and stand within 10 feet of the board
- Connect through the app, not the phone’s Bluetooth menu
- Ask the staff for the board’s current angle before you start
Who it suits
Kilter is widely called the friendliest of the LED boards. Climbing Magazine calls it “much more beginner-friendly, with large, grippy holds”. The label fits how regulars talk: they broadly agree Kilter grades run softer than MoonBoard grades. One thread on the difference between the boards concludes the Kilter is easier to start on. The MoonBoard is harder across the board.
The caveat is that it is still a training wall. A separate r/bouldering thread titled “is the Kilter board supposed to be THIS hard?” answers its own question. Board climbing assumes some strength, and steep angles punish newcomers. Grading is also a moving target. Climbers on r/bouldering describe Kilter grades as inconsistent, with some problems sandbagged like Tension Board climbs.
TipThe app’s grades are approximate, and the same problem climbs very differently at 45 degrees and up. On adjustable boards, the angle is part of the difficulty.
The board suits climbers who want measurable, repeatable sessions: set a problem, chase the send, log it. It suits travellers too, since the shared database means a familiar problem is waiting in the next city’s gym. For best bouldering in Berlin, training areas like bright site’s are part of the argument.
The Bottom Line
- The Kilter Board is an app-driven LED training wall, launched in 2018 by Colorado hold maker Kilter.
- Four nested Original sizes (16x12, 12x12, 8x12, 7x10) share one climb database; the Homewall family adds 10x10 and 10x12.
- Angles run 0 to 70 degrees in 5-degree steps; 40 is the default, and gyms often fix 40 to 50.
- The original app was taken down on 26 March 2026. The new app needs a fresh account, with data reclaimable via kilterboard.io/claim.
- Verified homes for a board: The Climbing Hangar venues (UK), boulderbar Wienerberg (Vienna), urban apes bright site (Berlin).
