,If you’re planning a move, renovation, or temporary transition, one of the first questions that comes up is how much storage space you actually need. Anyone planning a move to Staunton, VA quickly realizes how much furniture, boxes, and everyday belongings can add up in a three-bedroom home.

This guide walks through the most common storage unit sizes for a three bedroom house, explains what typically fits, and helps you think through the details that actually make a difference. For a room-by-room breakdown of what fits in each unit, our storage unit size guide walks through common layouts and use cases.
Quick answer: the most common sizes that work
Most three bedroom homes need more space than people expect. Furniture alone can fill a unit quickly, especially once you factor in mattresses, appliances, and boxed items from closets and kitchens.
10x15 is the starting point for most people
A 10x15 storage unit is often where people begin when storing a three bedroom home. It can work well for storing furniture from most rooms, but not everything.
This size typically fits several mattresses, a couch, a dining table, dressers, and a moderate number of boxes. It is a solid option if you are downsizing or only storing part of your home during a move.
10x20 for a whole three bedroom home, including larger furniture sets
A 10x20 unit is the most common recommendation for a full three bedroom house. This size can usually hold furniture from all bedrooms, a living room set, dining furniture, appliances, and stacked boxes.
If you are storing your entire household, this is often the safest and most flexible choice.
10x30 for big homes, garages, or the whole household plus outdoor gear
A 10x30 unit is best for larger three bedroom homes or households with full garages.
