How to Choose the Right Size Shed or Garage

Choosing the right outdoor storage building comes down to balancing what you need to protect today with how much property space you have available. Pick a building that is too small, and you'll run out of floor space within months; pick one that is too large, and it can overpower a modest yard.

 

Whether you need a compact lean-to for garden tools, a heavy-duty metal garage for a vehicle, or a versatile portable fabric shelter, this guide will help you match your storage requirements and property size to the ideal solution from ShelterLogic.

 

Step 1: Inventory Your Storage Items

Before measuring your yard, list everything you plan to store inside your shed or garage. Outdoor gear generally falls into four primary storage tiers:

  • Compact Storage (Under 50 sq. ft.): Push mowers, hand tools, hose reels, trash cans, patio cushions, and seasonal lawn decor.

  • Small Storage (50 to 100 sq. ft.): Riding mowers, snowblowers, bicycles, ladders, grills, and stacked lawn chairs.

  • Medium Vehicle & Equipment Storage (100 to 200 sq. ft.): Single compact cars, ATVs, riding mowers, zero-turn tractors, workbench setups, or bulk firewood.

  • Large & Heavy-Duty Storage (200+ sq. ft.): Trucks, SUVs, boats, RVs, commercial equipment, multi-vehicle parking, or large agricultural machinery.

Pro Tip: Calculate the total square footage your equipment occupies, then add 25% to your estimate. This safety buffer ensures you have room for walking paths, shelving kits, and future purchases without crowding your floor space.

 

Step 2: Select Your Material & Building Style

ShelterLogic offers two primary categories for storage buildings and garages, each catering to different durability goals, mobility requirements, and installation preferences.

 

Metal Sheds

Metal buildings provide long-term, permanent protection. Built from galvanized or Galvalume steel, metal sheds and garages resist harsh weather, pests, fire, and rot while keeping high-value vehicles and equipment secure year-round. They work best on established residential or commercial properties and require a level concrete pad or timber foundation frame.

  • Metal Sheds (Arrow®): Perfect for everyday lawn tools, riding mowers, and home workshops.

 

Portable Fabric Sheds & Garages (Shed-in-a-Box®, Garage-in-a-Box®, ShelterCoat®, ShelterTube®)

Fabric structures deliver flexible, quick-assembly coverage at an accessible price point. Constructed with heavy-duty steel frames paired with ripstop polyethylene or PVC covers, portable sheds and garages require no permanent foundation. They are ideal for seasonal vehicle parking, renters, or temporary site storage.

  • Portable Fabric Sheds (Shed-in-a-Box®): Compact units designed for rapid assembly in tight yard spaces.

  • Portable Fabric Garages (Garage-in-a-Box®, ShelterCoat®): Mid-to-large shelters with drive-through clearance, built to protect cars, trucks, boats, and RVs.

Step 4: Measure Your Property and Plan Site Access

Fitting the footprint of a shed or garage onto your property is only part of the planning process. Be sure to account for these crucial layout factors:

  • Check Zoning & HOA Setbacks: Local zoning rules typically require set clearance distances (usually 3 to 5 feet) between your structure and adjacent property lines, fences, or your home.

  • Allow Room for Entry & Turn Radius: Ensure there is adequate drive-in space for vehicles or wide turn-in clearance for riding mowers. Factor in swinging metal doors or roll-up/zippered fabric garage doors.

  • Check Vertical Clearance: Measure overhead space to clear tree branches, roof eaves, and power lines. Peak roof heights and door clearances can range from 6 feet on compact sheds to over 16 feet on heavy-duty fabric garages.

  • Prepare the Site Base: Metal sheds and garages require a flat, level concrete slab, wood deck, or floor frame kit. Portable fabric garages can be placed directly on gravel, dirt, or grass using proper auger or drive-in earth anchors.

 

Finding the Right Balance

If your yard space allows, choosing a slightly larger unit prevents outgrowing your building down the road. For general household storage, an 8' x 10' metal shed or 10' x 10' fabric shed covers everyday lawn equipment, while a 12' x 20' Garage-in-a-Box® or metal garage offers the optimal balance of space for vehicles, boats, and heavy equipment.
