Size reference
Standard gun safe dimensions.
Measured exterior (steel walls + fire board add 2–4 in per side beyond interior capacity). Small 8–10 gun: ~52–58 in H × 17–25 in W × 14–20 in D, 150–410 lb. Medium 20–30 gun: ~55–65 in H × 28–32 in W × 20–25 in D, 300–700 lb. Large 40–60 gun: ~60–72 in H × 28–42 in W × 22–28 in D, 600–1,100+ lb. Fire-rated models weigh 30–50% more than non-rated safes of the same size.
Run a check
Will it fit?
On moving day
Moving tips.
- 01Confirm the exterior dimensions (not the advertised interior capacity) before delivery day — steel and fire board add 2–4 in per side.
- 02Move the safe with its narrower side facing the opening, usually depth-first, and pull the entry door off its hinges to reclaim 1.5–2 in.
- 03Lay 3/4 in plywood runway sheets over hardwood and tile — a loaded dolly puts ~300 lb per wheel and cracks tile in seconds.
- 04For anything over 300 lb, hire professional safe movers; verify the destination floor can carry the point load before the move, not after.
Measure smart
What to measure.
Four numbers decide nearly every fit check. Get these right and the rest follows.
- 01The item's width, height, and depth at its widest points, including handles, feet, and any fixed trim.
- 02The smallest face of the item and its diagonal, which decide whether tilting it lets a long piece clear a tight opening.
- 03Every opening on the route: the door width, the hallway and any turn, the stair width, and the elevator door, not just the room you want it in.
- 04The weight, especially for appliances and solid-wood pieces, so you know how many people and what equipment the move needs.
Don't make these
Common mistakes.
Most “it didn't fit” stories trace back to one of these oversights.
- ⚠Measuring the room but forgetting the doorway, hallway turn, or stair landing the item has to pass through first.
- ⚠Ignoring the diagonal. Many pieces only clear a narrow door when tilted, which needs the diagonal, not the flat width.
- ⚠Leaving legs, doors, drawers, or cushions on. Removing them often saves the few inches that decide the fit.
- ⚠Assuming a published size matches your exact model. Compact, oversized, and apartment versions vary by several inches.
Frequently asked
Questions we keep getting.
What are the standard dimensions of a gun safe?
Residential gun safes fall into three rough tiers. A small 8–10 gun safe is about 52–58 in tall, 17–25 in wide, and 14–20 in deep (150–410 lb). A medium 20–30 gun safe is roughly 55–65 in tall, 28–32 in wide, and 20–25 in deep (300–700 lb). A large 40–60 gun safe runs 60–72 in tall, 28–42 in wide, and 22–28 in deep (600–1,100+ lb). Always use the exterior spec, not the interior capacity dimension.
01How much does a gun safe weigh?
Anywhere from about 150 lb for a small 8-gun safe to over 1,100 lb for a large 48–60 gun fire-rated model. Fire insulation alone adds 30–50% to the weight, so a fire-rated safe is far heavier than a non-rated safe of the same external size. Check the shipping weight on the spec sheet — it is the number that determines what equipment and how many people you need.
02Will a gun safe fit through a standard door?
Usually yes. Most residential safes are 20–32 in on their narrower dimension, which clears a 32 in interior door or a 36 in exterior door when you orient the narrow side to the opening. Large 40-gun-plus safes (38–42 in wide) may need the door pulled off its hinges for an extra 1.5–2 in. The physical fit is rarely the problem — the weight is.
03Can my floor support a gun safe upstairs?
A 600 lb safe on a ~3 sq ft footprint concentrates about 200 lb per square foot — roughly five times the 40 lb/sq ft live-load most residential floors are rated for. Position the safe directly over a load-bearing wall or a floor joist, and for safes over 500 lb on an upper floor, consult a structural engineer. A concrete slab on grade has no practical residential weight limit.
04Do I need professionals to move a gun safe?
For any safe over about 300 lb, yes. The combination of extreme weight and a high center of gravity makes a tipping safe nearly impossible to recover and capable of serious injury or property damage. Professional safe movers use a 1,000+ lb-rated dolly, ratchet straps, and plywood runway sheets, and typically charge $200–$800 depending on weight, stairs, and access.
