Choosing the right size for your metal garage is one of the most important decisions you’ll make when planning your project. Whether you need a simple one-car unit or a multi-bay workspace, the right dimensions can ensure your building is functional, cost-effective, and future-ready. At Robert & Sons Metal Buildings, we help clients in Dallas and across North Texas build garages that are just the right fit—no wasted space, no regrets.
1. Start with What You’re Storing
Begin by listing everything the garage needs to accommodate. Is it just for parking a vehicle? Do you need room for tools, equipment, or hobby supplies? Common items include:
- Cars, trucks, or SUVs
- RVs, boats, or trailers
- Lawnmowers, ATVs, or recreational gear
- Workbenches and shelving
- Storage bins, boxes, or seasonal décor
2. Consider Common Garage Sizes
Here are a few standard garage sizes to use as a starting point:
- One-Car Garage: 12′ x 20′ to 14′ x 24′ – fits most sedans and some small SUVs
- Two-Car Garage: 20′ x 20′ to 24′ x 30′ – fits two vehicles with room for light storage
- Three-Car Garage: 30′ x 30′ or larger – accommodates three vehicles or a mix of cars and workspaces
- RV Garage: 14’+ height with custom depth – built to fit taller vehicles and trailers
These sizes can be adjusted based on your layout, door size, and accessory needs.
3. Think About Height
Most standard metal garages range from 8′ to 12′ tall, but your use may require more height. Consider what you’ll store or work on inside. Taller walls may be needed for lifts, stacked storage, or future additions like lofts or mezzanines.
4. Plan for Maneuvering and Clearance
Make sure to leave room for moving around inside. Vehicles need space for opening doors, walking paths, and loading or unloading cargo. If your garage will serve as a workshop, you’ll also want extra width and depth around workbenches or tools.
5. Future-Proof Your Space
One of the biggest regrets we hear is, “I wish I’d gone bigger.” It’s often more affordable to build slightly larger now than to expand later. Think about your plans for the next 5–10 years. Will you buy a boat? Start a side business? Add new equipment or hobbies? Building with flexibility in mind today saves time and money down the road.
6. Check Zoning and Setback Rules
Before you finalize your design, make sure your planned garage size complies with local Dallas zoning regulations, easements, and setbacks. We help our clients navigate this process to avoid surprises during permitting and inspections.
7. Customize with Doors, Windows, and Storage
Your garage is more than four walls and a roof—it’s a space that should work for you. Think about:
- Number and size of roll-up or sectional doors
- Walk-in access doors
- Window placement for natural light
- Shelving, cabinetry, and tool storage
- Insulation and climate control for year-round use
