When it comes to installing an electric fireplace insert, the old carpenter’s adage “measure twice, cut once” couldn’t be more applicable. In fact, we might even suggest “measure thrice, install once” for this particular home improvement project. Accurate measurements are the foundation of a successful electric fireplace installation, ensuring a perfect fit, optimal performance, and a stunning visual impact in your living space.
Why Precise Measurements Matter
Before we dive into the nitty-gritty of taking measurements, let’s explore why this step is so crucial:
- Proper Fit: An electric fireplace insert that’s too small will leave unsightly gaps, while one that’s too large simply won’t fit into the existing space.
- Optimal Performance: Correct sizing ensures proper ventilation and heat distribution, maximizing the efficiency of your electric fireplace.
- Aesthetic Appeal: A well-fitted insert looks seamless and professional, enhancing the overall appearance of your room.
- Cost-Effectiveness: Avoiding measurement errors prevents the need for costly modifications or returns.
- Safety: Proper sizing reduces the risk of overheating and ensures the insert functions as intended.
Essential Measurements for Your Electric Fireplace Insert
To ensure a perfect fit for your electric fireplace insert, you’ll need to take several key measurements. Here’s a comprehensive list:
- Opening Width: Measure at the front, middle, and back of the fireplace opening.
- Opening Height: Measure from the hearth to the top of the opening at the front and back.
- Opening Depth: Measure from the front to the back of the fireplace at several points.
- Hearth Depth: Measure from the front of the fireplace opening to the edge of the hearth.
- Mantel Height: Measure from the hearth to the bottom of the mantel, if present.
- Clearances: Measure the space around the fireplace for any obstructions.
- Electrical Outlet Location: Measure the distance to the nearest outlet.
Tools of the Trade
To ensure accurate measurements, you’ll need the right tools. Here’s what you should have on hand:
- Tape Measure: A sturdy, retractable tape measure is essential.
- Laser Measure: For quick and precise measurements, especially in hard-to-reach areas.
- Level: To ensure your measurements are straight and true.
- Notepad and Pen: For recording your measurements.
- Camera: To document the space and any potential obstacles.
- Flashlight: For better visibility in dark corners.
- Helper: An extra set of hands can be invaluable for holding the tape measure or providing a second opinion.
Step-by-Step Measurement Guide
Now that we’ve covered the basics, let’s walk through the measurement process step by step:
1. Clear the Area: Remove any debris, ashes, or old fireplace accessories from the existing fireplace.
2. Measure the Opening Width:
- Measure at the front of the opening
- Measure at the middle of the opening
- Measure at the back of the opening
3. Measure the Opening Height:
- Measure at the front of the opening
- Measure at the back of the opening
- Record the smallest measurement
4. Measure the Opening Depth:
- Measure from the front to the back at several points
- Record the smallest measurement
5. Measure the Hearth Depth:
- Measure from the front of the fireplace opening to the edge of the hearth
6. Measure the Mantel Height (if applicable):
- Measure from the hearth to the bottom of the mantel
7. Check for Obstructions:
- Look for any protruding bricks, mortar, or metal components
- Measure any obstructions and note their locations
8. Locate the Electrical Outlet:
- Measure the distance from the fireplace opening to the nearest outlet
- Note whether the outlet is on the left or right side

Common Measurement Mistakes to Avoid
Even with the best intentions, it’s easy to make measurement errors. Here are some common pitfalls to watch out for:
- Assuming the opening is square: Many fireplace openings are not perfectly square, so measure at multiple points.
- Forgetting about clearances: Remember to account for any required clearances around the insert.
- Neglecting to measure depth: A fireplace that’s wide enough might still be too shallow for your insert.
- Ignoring obstructions: Small protrusions can make a big difference in fit.
- Rounding measurements: Always use exact measurements, down to the fraction of an inch.
- Measuring only once: Always double-check your measurements for accuracy.
- Not considering the electrical requirements: Ensure you have a proper power source within reach.
Choosing the Right Electric Fireplace Insert
Once you have your measurements, it’s time to select the perfect electric fireplace insert. Here’s a comparison table of different insert sizes and their ideal opening dimensions:
| Insert Size | Ideal Opening Width | Ideal Opening Height | Ideal Opening Depth |
| Small | 23″ – 26″ | 19″ – 22″ | 10″ – 12″ |
| Medium | 27″ – 30″ | 23″ – 26″ | 12″ – 14″ |
| Large | 31″ – 34″ | 27″ – 30″ | 14″ – 16″ |
| Extra Large | 35″ – 38″ | 31″ – 34″ | 16″ – 18″ |
This table provides a general guide for choosing an electric fireplace insert based on the size of your fireplace opening. The “Small” size is suitable for openings with a width between 23 and 26 inches, a height between 19 and 22 inches, and a depth between 10 and 12 inches. The “Medium” size fits openings with a width of 27 to 30 inches, a height of 23 to 26 inches, and a depth of 12 to 14 inches.
