Garage door replacement cost increases significantly with door size. Larger doors require more materials, heavier-duty hardware, and longer installation times, all of which raise total cost.
This guide breaks down garage door replacement cost by door size, focusing on single and double garage doors.
Average Garage Door Replacement Cost by Door Size
Installed cost ranges typically fall between:
- Single garage door: $700 – $2,500
- Double garage door: $1,200 – $5,500
Prices vary based on material, insulation, and labor rates, but size is one of the largest cost drivers.
Single Garage Door Replacement Cost
A single garage door is usually 8–9 feet wide and is common in older homes or single-car garages.
Typical cost (door only):
- $400 – $1,400
Installed cost (including labor):
- $700 – $2,500
Single garage doors cost less because:
- Less material is required
- Doors are lighter, requiring simpler springs and tracks
- Installation is faster
They also place less stress on mechanical components over time.
Double Garage Door Replacement Cost
A double garage door is typically 16 feet wide and covers a two-car garage opening.
Typical cost (door only):
- $800 – $4,000
Installed cost (including labor):
- $1,200 – $5,500
Double garage doors cost more because:
- Heavier panels require stronger springs and tracks
- Installation takes longer and may require additional labor
- Framing adjustments are more common
Cost differences are more pronounced with premium materials or insulation upgrades.
How Door Size Affects Installation Cost
Larger doors increase:
- Hardware requirements
- Spring strength and tension
- Labor time
- Risk of future mechanical issues if improperly sized
Improper installation on large doors often leads to premature spring or opener failure.
Can You Change Garage Door Size?
Most replacements use the existing opening size. Changing door size may be required when:
- Remodeling the garage
- Converting two single doors into one double door
- Expanding or narrowing the garage opening
Resizing almost always increases project cost due to framing and structural work.
