Dimensions of a Double Garage

The dimensions of a double garage refer to the required width, length, and height measurements needed to safely and comfortably accommodate two vehicles. In addition to the vehicles’ dimensions, maneuvering space, door swing areas, and additional storage space play a key role. Thorough planning takes into account both minimum requirements and practical comfort factors to ensure long-term usability.

Standardized Sizes at a Glance

Typical guideline values for garages are based on established construction and usage requirements:

Single parking space: approx. 3.00 × 6.00 m
Double parking space: approx. 6.00 × 6.00 m
Extended version: from approx. 6.50 m width

These values serve as a planning basis and are particularly relevant for industrially manufactured solutions, where modular dimensions are used.

Size Table for Double Garages

Category Width (m) Length (m) Description
Minimum size approx. 5.50 approx. 5.50 Functional, but limited comfort
Standard size approx. 6.00 approx. 6.00 Proven solution for two vehicles
Comfort size 6.50 to 7.00 6.50 to 7.00 Additional maneuvering and storage space
Large-scale solution from 7.00 variable For larger vehicles or additional use

Space Requirements per Vehicle

For practical use, the width per parking space is crucial:

Minimum value: approx. 2.50 m
Practical value: 2.75 to 3.25 m

These values allow vehicle doors to open and ensure safe entry and exit. For wider vehicle types (e.g. SUVs), the higher range should be considered.

Garage Door Dimensions

The opening width of the door directly affects the entry situation:

Single opening: approx. 2.25 to 2.50 m
Double opening: approx. 4.50 to 5.50 m
Height: approx. 2.00 to 2.25 m

A sufficiently sized door reduces maneuvering effort and minimizes the risk of damage.

Garage Height Planning

The internal height is often underestimated but is functionally crucial:

Standard height: approx. 2.20 to 2.40 m
Extended height: recommended for large vehicles or roof attachments

Note the difference between clear internal height and the actual clearance height at the door.

Differences Between Internal and External Dimensions

When planning, a distinction must be made between external dimensions and usable internal space:

  • Wall thickness reduces effective internal width
  • Prefabricated garages often have standardized external dimensions
  • Internal dimensions are decisive for actual usability

Precise coordination helps avoid later usage limitations.

Impact of Dimensions on Costs

The size of the garage has a direct impact on investment costs:

  • Larger areas increase material and transport costs
  • Installation costs rise with increasing dimensions
  • Additional features (door, electrics, extensions) influence the total price

Typical price ranges start in the lower segment and increase significantly with size and features.

Common Planning Mistakes

Frequent errors in dimensioning:

  • Focusing only on minimum dimensions
  • Insufficient door width
  • Lack of storage space
  • No consideration of future vehicle sizes

In practice, these points lead to limited usability.

Step-by-Step: Dimensioning a Double Garage

  1. Analyze vehicle sizes
  2. Define additional space requirements (e.g. bicycles, workbench)
  3. Plan comfort allowances (at least +0.50 m)
  4. Determine door width and height
  5. Align internal and external dimensions
  6. Check legal building regulations

FAQ: Dimensions and Planning of Double Garages

What is the minimum size for a double garage?
At least approx. 5.50 × 5.50 m, but with limited comfort.

What size is practical for everyday use?
A version from approx. 6.50 m width offers significantly better usability.

How much space should be planned per vehicle?
At least 2.75 m, ideally up to 3.25 m.

What door width is recommended?
For two vehicles, approx. 4.50 to 5.50 m.

Why are larger garages beneficial in the long term?
They provide reserves for larger vehicles and additional storage space.
