No-Drill Storage Planner

Adhesive hook packets promise their best-case number on a perfect surface. This planner starts from the maker's rating for your hooks, then applies a surface factor and a 25% safety margin, and tells you how many hooks the load genuinely needs — or tells you to switch to a rail, a rod, or furniture instead.

Built-in module

Adhesive Hook Weight Calculator — the derated hook count above is the module, with surface and safety factors shown.

How it works

Planned allowable per hook = maker rating × surface factor (painted drywall 0.6, tile 0.8, glass 0.9, wood door 0.85, textured wallpaper 0.4) × 0.75 safety margin. These are conservative planning factors for general guidance — your product's own instructions always win.

How to use it

  1. Weigh the item (bathroom scales work: weigh yourself holding it, then without).
  2. Find the per-hook rating on your packet — not the multipack headline.
  3. Choose the surface honestly; painted drywall is not tile.
  4. Wait the full cure time on the packet before loading, and never hang heavy or breakable items over a bed, cot or walkway.

Frequently asked questions

Why is the planned number so much lower than the packet?

The packet number is a best case: ideal surface, perfect prep, laboratory pull direction. Real walls are painted, humid and loaded at an angle. The derating is what makes the plan trustworthy — a hook that fails at 2 a.m. is not storage.

This is general guidance, not a guarantee — what does that mean?

Adhesive performance varies by brand, paint, humidity and prep, so no calculator can guarantee a bond. Use the plan to size generously, follow your product's instructions, and keep anything fragile or heavy off adhesive fixings entirely.

What is the best no-drill option for heavy things?

Freestanding: a ladder shelf, an over-door rail (which loads the door, not the wall), or furniture with storage built in. The planner names these when your weight goes past what hooks should carry.
