A 15-inch gas pizza oven is a strong fit for cooks who want propane convenience with more turning room than a compact 12-inch format. The current Big Horn Outdoors dual-burner model lists a 14.7-inch cooking area, two independently controlled burners, 23,000 BTU total output, a built-in thermometer, and a claimed maximum of 1,070°F. Those numbers describe capability; they do not mean every pizza should be baked at maximum heat.
The Extra Room Is the Main Reason to Size Up
A 12-inch pizza is easy to maneuver on a larger deck because there is space around the dough for a peel and rotation. A 14-inch family pizza uses more of the surface and requires better launch accuracy. The useful question is therefore not “Can a 14-inch pizza fit?” but “Can I comfortably turn the pizza I make most often?”
You can compare the current product details on the 15-inch dual-burner gas pizza oven page.
Dual Burners Matter When the Oven Has a Hot Side
Independent burners give the cook another way to balance heat after preheating. If one side colors the rim too quickly, reduce that burner rather than lowering the entire oven. If the deck needs recovery, let the oven rebuild heat before the next launch instead of keeping both burners at maximum throughout the session.
The troubleshooting method in Read the Crust Before Changing the Heat is especially useful here because it separates deck problems from top-heat problems.
Use the Built-In Thermometer as One Signal
A chamber thermometer is convenient, but the dough touches the stone. If the manual permits it, a surface thermometer can help you learn how the deck behaves at the beginning of a session and after several pizzas. The goal is a repeatable baseline, not a universal number.
Think About the Table Before Buying the Oven
A 15-inch format needs a stable outdoor surface with room for the oven footprint, the hose, the cylinder, a peel, and a safe standing position. A table that barely fits the oven may still be a poor work station. Keep the propane cylinder upright and away from heat, and follow the clearances in the manual.
If travel and compact storage matter more than deck room, the portable gas travel guide is a better framework for choosing size.
Match the Heat to the Pizza Style
Thin high-heat pizzas need a different balance than a heavily topped pie or a New York-style pizza that benefits from more time. A powerful gas oven is useful because it can be adjusted; using it well means knowing when not to run it at full output.
Who Should Buy the 15-Inch Format?
Choose it when you regularly make 12- to 14-inch pizzas, want simple propane control, and have enough outdoor space to operate safely. Choose a smaller oven when storage and transport dominate the decision. Choose live-fire pellet equipment when managing the fire is part of the experience you want; the beginner fuel comparison lays out those trade-offs.
