Most home spray walls end up as a random pile of holds that looked good in the online store but don't actually climb well together. You end up with 50 crimps, three jugs, no footholds, and every problem feels the same. The holds you pick should be driven by the styles of climbing you want to train, not the other way around. What follows is how to think about hold selection for a home spray wall: designing core problems first, choosing the right textures, and building a wall that actually makes you better.
Problems first. Holds second.
Know Your Wall Before You Shop
Your wall angle and size dictate everything about your hold selection. For most spray walls, 40–50° is the sweet spot.
Density isn't a flat average across the whole wall. Think in zones. The heart of the wall, that middle section where most of your climbing happens, should be packed at around 5–7 holds per square foot. The top and bottom need less since you're mostly hitting finish holds or starting there. Same with the sides.
Design Problems First, Buy Holds Second
Instead of buying a random assortment and then trying to set with what you have, plan a handful of core problems or movement types you want on your wall. Let those drive your hold shopping list. Know what you want from your wall before you buy holds.
Example core problems to design around:
A power problem, 4–5 hard moves on big holds with difficult body positions. Think roof-style moves between slopers where you have to keep tension through a full extension, or big throws to a pinch while cutting feet. This tells you to prioritize a few quality macros and pinch sets.
A crimp-strength problem, Technical, sustained small-edge climbing. Tells you to buy a set of edges in 2–3 depths.
A compression problem, Wide moves on opposing holds where you're squeezing inward to stay on the wall. Tells you to buy holds that can be set in opposition to create width.
Map these out roughly on your wall. Chalk marks, tape, whatever works. Think about the type of rock you climb on most outside. If your local crag is all pockety limestone, lean your hold selection that direction. If you're projecting on crimpy granite or sandstone slopers, make sure your wall reflects that. A good spray wall should prepare you for the climbing you actually do, not be a generic training tool. Now you know what shapes, sizes, and quantities you actually need, and you're buying with intent instead of guessing.
Build a Dedicated Foothold Grid
Most home spray walls make the mistake of letting hand holds supply foot options. Hand holds are rarely small enough to force hard foot moves. Better approach: install a grid of small footholds and screw-on jibs across the wall, independent of any particular problem.
You get non-tracking problems where only the hand holds are defined and feet are open. That's how a lot of outdoor climbing actually works. You read the rock, find your own feet, make decisions on the fly. Tracking every foothold in every problem removes that skill from your training. Open feet also let you tailor difficulty on the same hand sequence, a problem that feels impossible with high feet might click when you find a low toe or a sneaky backstep on a jib you placed for a completely different reason.
Hold Types: What Your Problems Tell You to Buy
Translate your core problems into a shopping list. What each hold type does on a spray wall:
Jugs, Warm-ups, endurance circuits, rest positions. You need fewer than you think on a steep wall. Don't let them eat up prime wall space.
Crimps/Edges, The bread and butter. Buy a range of depths. Small, cheap, and you can always add more.
Slopers/Macros, Not required and often hard to get right on a home wall. If you do buy them, a few quality ones beat a pile of mediocre ones. They're expensive and take up space, so be deliberate.
Pinches, Force full-body engagement. Often overlooked on home walls. A set of varying widths opens up a whole different style of climbing.
Footholds/Screw-ons, The most common thing home walls are missing. Cheap, small, and they make your setting way better. Buy more than you think.
Volumes, Worth it if you have the space and budget. Even 2–3 flat volumes in the middle of the wall add a dimension that small holds can't.
Spray, Mirror, or Approximate Mirror Setting
There are a few ways to approach how you place holds on your wall. Each one serves a different purpose and you can mix them.
Spray, Holds packed close together without any particular plan. No symmetry, just fill the wall and let the climbing reveal itself. This is the classic spray wall approach and it works well for creative setters with lots of homewall setting experience. Sprays when done right are amazing, but the most difficult to pull off. It takes months of tweaking.
Full mirror, Identical hold placement, symmetrically flipped left-to-right. This only works if the holds you're buying are symmetrical or sold as mirrored pairs/sets. The payoff: you instantly double your problem count and expose imbalances between your left and right sides. If a problem feels easy on your dominant side and impossible mirrored, you've found a weakness worth training.
Approximate mirror, Similar movement and difficulty, but using different holds in roughly mirrored positions. More practical for most spray walls since you don't need to buy everything in pairs. You're replicating the movement pattern, a left-hand gaston into a right-hand sloper, rather than the exact holds. Still exposes imbalances while giving you more creative freedom.
When to use which: Full mirror if you're building a dedicated training wall and want measurable symmetry. Approximate mirror for most home spray walls where space, budget, and hold variety make an exact copy impractical. Spray for the zones you want to keep loose and unstructured. Most good home walls end up being a mix of all three.
Texture: How It Feels Under Your Fingers
Forget material science. What actually matters when you're climbing 3–4 days a week on the same wall is how the holds feel on your skin over time.
Wood holds, Most skin-friendly option. You can train longer and more frequently without shredding your tips. Great for high-traffic positions.
Plastic holds (PU/PE), More grip variety, more shapes available, closer to what you'll find at the gym. Rougher textures build contact strength but eat skin faster.
Used holds, Gym de-sets are a legitimate budget play. Worn texture is actually an advantage on a home wall. Smoother on skin and forces better technique. Ask your local gym when they're stripping routes.
Mix textures intentionally. Wood in the positions you'll grab most. Plastic for variety and specific shapes you can't get in wood. Used holds to fill density gaps without blowing your budget.
Sand your new holds before you climb on them
Most commercial plastic holds ship with aggressive texture designed for high-traffic gyms where hundreds of hands fill them with chalk and grease within weeks. On your home wall, that break-in never happens. You'll be climbing on sandpaper for months, shredding skin and cutting sessions short.
Knock them down with 150-grit sandpaper before you ever bolt them on. Do this outdoors or in a ventilated space, the dust from polyurethane holds isn't something you want to breathe. Work the sandpaper across the gripping surfaces. Light, even pressure. Check frequently, you want to remove the sharp peaks of texture while leaving enough grit for friction.
Stop when you can drag your fingertips across the surface and it feels grippy but not abrasive. If you're unsure, sand less. You can always take more off, but you can't add it back. A few minutes per hold saves the hassle of torn skin and lets you actually train.
- Climb a month; note holes
- Buy for the hole, not the sale
- Sand new PU before hard sessions
Common Mistakes
Buying everything at once. Start at 60–70% density. Climb on it for a few weeks. The gaps in your setting will tell you exactly what to buy next.
Too many of the same depth and incut of crimps, not enough variety.
No footholds. Forces tracking and kills creativity.
Not planning for mirror problems. Retrofitting symmetry is harder than building it in from the start.
Your hold collection will evolve. The best home spray walls aren't built in one order. They're built over months of climbing, identifying what's missing, and adding with purpose. Start with your problems, not your holds. The rest fills in.
