The size of the home safe matters for a few reasons. Small safes have a compact design to fit in any small area, but they have limited space inside. If you have bigger valuables or electronics, you’ll want to consider a large home safe. Most large and small home safes can be mounted to a wall or bolted to the floor to securely store the safe in your home. Make sure to know where you’ll be storing the safe to choose a size, pick where you’ll put it to decide how big it can be, and consider how much you’ll want to put inside.
