Large Fireplace Doors — 48″+ Wide & Oversized Openings, Custom Made
Fireplace opening wider than 48″ or taller than 34″? You're in the right place — oversized openings are one of our specialties. Standard doors stop where your fireplace begins; ours are engineered for exactly this size range and built to your measurements, to the 1/8″.
Why large fireplaces need "fixed end panels"
Glass doors have a practical limit on how wide each operable panel can swing before the frame and hinges carry too much weight. The solution for openings over ~48″ wide (or ~34″ tall) is a door with fixed end panels: stationary glass sections on the left and right, with fully operable doors in the center. You keep the clean full-glass look and everyday access to the firebox — the frame keeps its rigidity at any width.
What sizes can we build?
We routinely build doors for openings 48–72″ wide, and taller-than-standard openings as well. Most of the door lines in our custom fireplace doors collection can be configured with fixed end panels for oversized openings — and because every EF door is made to order in the USA, "custom" here means your exact dimensions, not the nearest stock size.
Measuring a large opening
Big openings are less forgiving of measurement shortcuts. Measure the width in three places (top, middle, bottom) and the height in three places (left, center, right), to the nearest 1/8″ — masonry openings are rarely perfectly square. Our guide walks through it step by step: how to measure your fireplace for glass doors. Arched opening? See arched fireplace doors — we measure those by width, side height and center peak.
