How to Measure and Replace Your Fireplace Glass – A Step-by-Step Guide

Your fireplace glass plays a critical role in both safety and efficiency. Whether it’s cracked, fogged, or simply outdated, replacing it is easier than you think. In this guide, we’ll walk you through how to measure and replace your fireplace glass to ensure a perfect fit every time.

Why Proper Measurement Matters

Getting the right measurements ensures that your new ceramic fireplace glass will fit snugly, prevent heat loss, and protect your home from sparks. Ordering incorrectly sized glass could result in gaps, improper sealing, or potential safety hazards.

Step 1: Gather Your Tools

Before starting, you’ll need:

  • A tape measure (preferably one with 1/16-inch increments).
  • A notepad and pen to write down your measurements.
  • Protective gloves (especially if dealing with broken glass).
  • A screwdriver (if your fireplace has a retaining frame).

Step 2: Remove the Old Glass

Follow these steps to safely remove the old glass:

  1. Make sure your fireplace is completely cool before starting.
  2. If the glass is held by screws or clips, carefully remove them using a screwdriver.
  3. Gently lift out the glass panel. If it’s broken, wear gloves and handle with care.
  4. Clean the gasket seal and surrounding area to prepare for the new glass.

Step 3: Measure the Fireplace Glass

Accurate measurements are crucial. Here’s how to do it correctly:

  1. Measure width (left to right) – Take three measurements: top, middle, and bottom. Use the smallest measurement.
  2. Measure height (top to bottom) – Take three measurements from left, center, and right. Again, use the smallest number.
  3. Subtract 1/8 inch from each measurement to ensure a proper fit inside the frame.
  4. Determine the thickness (typically 3/16” or 1/4” for ceramic fireplace glass).

Step 4: Order the Right Replacement Glass

Now that you have the exact measurements, you can order custom-cut ceramic fireplace glass. Make sure to choose:

  • Robax or NeoCeram glass (designed for high temperatures).
  • The correct thickness and size.
  • Gasket & glue kits for proper sealing.

Step 5: Install Your New Fireplace Glass

Once your new glass arrives, follow these steps to install it:

  1. Place the new gasket seal around the edges of the fireplace opening.
  2. Position the new glass inside the frame, ensuring a snug fit.
  3. Secure it using retaining screws or clips (avoid overtightening).
  4. Double-check the fit and test the door seal before lighting your fire.
