16x8 Garage Door: Price, Installation, and Buying Guide
A 16x8 garage door is one of the most popular sizes for double-car garages. It offers enough width to accommodate two vehicles side-by-side while providing a clean, attractive look for your home’s exterior. Whether you’re replacing an old door or installing one for the first time, it’s important to know the right dimensions, opener requirements, and insulation options to make the best choice.
How Much is a 16x8 Garage Door?
The price of a 16x8 garage door varies depending on the material, style, insulation level, and brand.
- Basic non-insulated steel models: $800 – $1,200
- Insulated steel or aluminum models: $1,200 – $2,500
- High-end wood or custom designs: $2,500 – $5,000+
Extra costs may include installation, which can range from $300 to $700, and additional features like smart openers or decorative hardware.
What is the Rough Opening for a 16x8 Garage Door?
The rough opening for a 16x8 garage door should be exactly 16 feet wide and 8 feet high. This ensures the door fits perfectly into the frame without gaps. The header, side jambs, and floor should be level to avoid operational issues. A proper rough opening guarantees smooth installation and long-term performance.
What Size Garage Door Opener for 16x8?
For a 16x8 garage door, a 3/4 HP to 1 HP garage door opener is typically recommended.
- 3/4 HP: Suitable for standard steel doors.
- 1 HP: Better for heavier, insulated, or wooden doors.
What Size Torsion Spring for 16x8 Garage Door?
The torsion spring size depends on the door’s weight and height, not just the width. For a 16x8 steel door, springs are usually between 2” in diameter and 23–41” in length. However, always have a professional measure and install springs—improper sizing can cause serious safety hazards and damage.
What is a Good Insulated 16x8 Garage Door?
If you live in a region with extreme temperatures, an insulated 16x8 garage door is a smart investment. Look for models with:
- R-value of 12 or higher
- Polyurethane or polystyrene foam insulation
- Thermal break construction to prevent heat transfer
Top brands like Clopay, Amarr, and CHI offer highly insulated options that improve energy efficiency and reduce noise.

- Home improvement stores like Home Depot or Lowe’s
