There’s No Such Thing as a Standard Size Security Door—Here’s Why That Matters

If you're a homeowner in Glendale, AZ considering a security door upgrade, you've probably seen standard sizes like 36” x 84” or 42” x 96” thrown around. But here's the truth: there’s no such thing as a truly standard size security door—at least not one that fits your home perfectly.

Security doors are not one-size-fits-all, and treating them that way can result in poor fits, security vulnerabilities, and a look that doesn't quite complement your home.

Why “Standard” Sizes for Security Doors Don’t Actually Work

While certain dimensions are more common in the industry, every home is different. Shifts in framing, stucco build-outs, custom elevations, and architectural variations mean that no doorway opening is ever exactly 36” x 96” or 42” x 84”.

At Allied Iron, we often reference these common frame sizes:

• 36” x 84”

• 36” x 96”

• 42” x 96”

• 48” x 96”

But we never assume your door opening is an exact match. Instead, we custom-measure every opening to ensure a proper fit—because a slight misalignment can lead to poor sealing, reduced security, and even frame damage over time.

Why Customized Security Doors are Key—Functionally and Visually

A custom-fit security door isn’t just about measurements—it’s about matching your home’s architecture and your personal style.

With Allied Iron, you can personalize your security door with:

• A wide range of design patterns

• Powder coat color options to match trim or accents

• Different screen colors for airflow, sun protection, or privacy

• Hardware, like dual-cylinder deadbolts, lock guards, or upgraded decorative handles

Our goal is to blend form and function—a door that enhances both your home’s safety and its curb appeal.
