A standard 16x7 ft insulated steel garage door weighs 150-250 lbs. Single car doors (8x7 or 9x7) weigh 75-150 lbs. Weight depends on material, insulation, and panel thickness.
A 1/2 HP opener handles most single and standard double doors up to 250 lbs. Doors over 250 lbs (wood, oversized) need 3/4 or 1 HP openers. Use 1 HP for doors over 350 lbs.
Standard torsion spring systems need 12 inches of headroom above the door opening. Low-headroom hardware kits reduce this to 6-9 inches but cost more. Jackshaft openers need only 4-6 inches.
Basic steel doors cost $600-$1,200 installed, mid-range insulated steel $1,200-$2,500, and premium wood or custom doors $3,000-$8,000+. Material, insulation, and design complexity drive the price.
