Things to Consider Before Buying a Fireplace Grate
1. Fireplace Size
Measure your firebox carefully, both front and back width, as well as depth. Leave about 3 inches of clearance on each side for proper airflow and safe use.
2. Material Type
Cast iron is traditional and very durable, ideal for high heat. Steel bar grates can handle more weight and are often better for oversized logs.
3. Airflow & Leg Height
Higher legs (2.5″–4″) improve air circulation and ash control, helping wood burn more completely.
4. Basket Shape
Curved or self-feeding grates help logs roll inward, which can reduce the need for poking. Flat-bottom designs offer more control during fire-building.
5. Ease of Assembly
Some grates arrive fully welded and ready to use, while others require minimal setup.
6. Usage Frequency
If you burn daily, opt for a lifetime-grade steel or thick cast iron with strong welds and solid weight. Occasional users may prefer lighter options.
FAQs

Measure the width at the front and back, the depth, and subtract 6 inches from each dimension to ensure a proper fit.
