What is the standard garage size?

Standard garage dimensions: Width 2.5 meters, Length 5.0-5.5 meters. According to Article 4.1.5.3 of the 'Code for Design of Parking Garages' JGJ100-98: The minimum size for a small car parking space using perpendicular parking should be 5.3m (length) × 2.4m (width), with a minimum access aisle width of 5.5m in front of the parking space. According to Article 4.1.4 of the 'Code for Design of Parking Garages' JGJ100-98: The minimum distance between small cars and side walls should be 0.6m, and the minimum distance to front/rear walls should be 0.5m. Based on these regulations, the minimum indoor dimensions for a single parking garage should be: 4.8m (car length) + 0.5m (front clearance) + 0.5m (rear clearance) = 5.8m; 1.8m (car width) + 0.6m (left clearance) + 0.6m (right clearance) = 3.0m. Therefore, the minimum indoor garage size should be 5.8m×3.0m, with a minimum access aisle width of 5.5m in front of the garage.
I remember when my family built the garage, the standard dimensions were far from fixed. Typically, a single garage is about 12 to 14 feet wide and 20 feet deep, which can easily accommodate a regular sedan. However, if you own a large pickup truck or SUV, the width should be increased to 14 to 16 feet for comfort, otherwise, you might struggle to open the doors. A double garage is generally 20 feet wide and 20 feet deep, but for convenient access for two vehicles simultaneously, each door should ideally be 9 to 10 feet wide. As for height, 7 feet is the minimum, but nowadays, many larger vehicles require 8 to 9 feet of clearance to avoid scraping the roof, especially those with sunroofs. I also recommend leaving some extra space for storage when building a garage—like I did for tools and miscellaneous items—extending the depth to 24 feet makes it more practical. Additionally, regulations vary by region; for example, suburban areas might require larger dimensions to accommodate local climate conditions.
