Double vs. Single Iron Entry Doors: How to Choose
The 60-second decision
Ask three questions. (1) What's my rough opening? Under ~5 feet wide, you're a single (possibly with sidelights); over ~5 feet, both options open up. (2) What's the budget? Configuration is the top price driver — a double roughly doubles steel and glass (cost guide). (3) What's the house saying? A wide, symmetrical facade with a centered entry begs for a double; a compact or offset entry often looks better with a generous single.
How double doors work day to day
Most families operate one leaf — the active leaf — for daily traffic, while the passive leaf stays bolted at top and bottom and opens for furniture, deliveries, and parties. The meeting edge closes against an astragal (a vertical sealing strip on the passive leaf) that weather-seals the pair. It's one extra step when you want the full opening, and none on a normal day.
When a single door wins
Standard openings, tighter budgets, and heavy-weather practicality: one leaf means one perimeter to seal and the simplest lock-up. A single also concentrates the design — a heavily scrolled single door reads as jewelry on the facade. Want more light or presence without the width? Sidelights and a transom around a single door split the difference at a lower cost than a full double.
When a double door wins
Presence, symmetry, and clear width. A double turns the entry into the centerpiece of the elevation, and moving a piano, a sectional, or a crowd through a ~6-foot opening is effortless. On wide facades, a single door can look under-scaled — proportion is a real design constraint, not vanity.
Security and storm performance
Built right, both configurations are formidable: Abby doors are forged 12-gauge steel, and either can be fitted with impact glazing engineered to Florida Building Code standards for coastal zones — see are iron doors hurricane-proof?. On a double, verify the passive-leaf bolts engage steel (frame head and sill) — on a forged door they do; that's a question to ask of lighter-built imports.

Frequently asked questions
Are double iron doors more expensive than single doors?
Yes — configuration is the biggest price driver, and a double roughly doubles the steel and glass. Exact pricing is by quote since every Abby door is custom-built; see what iron doors cost.
How wide does my opening need to be for double iron doors?
Plan on roughly 61–74 inches of rough-opening width for common double units (two 30–37″ leafs), before sidelights or a transom. See the sizing guide.
Are double doors less secure than a single door?
Not when built in forged steel with proper passive-leaf bolts engaging the frame at head and sill. Ask how the passive leaf locks — on 12-gauge forged doors like Abby's it anchors into steel, not just weatherstripping.
Can double iron doors be hurricane-rated?
Yes. Like singles, double doors can be fitted with impact glazing engineered to Florida Building Code standards; Florida installations by Abby are done to local hurricane-code requirements.
My opening is too narrow for doubles — what are my options?
A single door with sidelights and/or a transom delivers much of the light and presence of a double in less width, at a lower cost. It's the most common compromise and often the better-proportioned one.
