Don't forget these essential items for installation:
Step 01
Grab a tape measure to find your room's length and width in feet. Good measurements are the first step to a beautiful floor.
Step 02
We automatically add a 10% baseline safety margin to cover standard planks, cuts, and errors. For herringbone or diagonal layouts, we recommend ordering more manually.
Step 03
Enter your price per square foot to get a realistic budget estimate. No more guessing games at the store!
| Wood Species | Janka Hardness | Recommended Use |
|---|---|---|
| Red Oak | 1,290 lbf | Standard residential flooring |
| White Oak | 1,360 lbf | High-traffic areas, moisture-prone |
| Hickory | 1,820 lbf | Maximum durability for busy homes |
| Walnut | 1,010 lbf | Living rooms & low-traffic luxury |
Note: Janka hardness ratings and baseline suggestions are intended for guidance only. Actual material performance and local pricing can shift based on specific milling, grading, and regional market trends.
The subfloor must be clean, flat, and dry. Check with a straightedge: deviations exceeding 3/16" over 10 feet should be leveled prior to laying planks.
On concrete subfloors or crawlspaces, a proper moisture barrier or PE underlayment film is critical to block rising dampness and prevent natural wood warping.
Leave a 1/2" expansion gap around the perimeter of the room. Use spacers during installation so that the timber can naturally adjust to seasonal climate shifts.

Hardwood is usually sold by the carton, not by the plank. Calculating your total area (plus a little extra for cuts) helps you figure out exactly how many boxes to buy, keeping your budget on track.
Measure the closet's length and width separately. Add this square foot area to your main room's total before applying the standard waste factor. This approach helps keep your overall floor plan consistent across adjoining spaces.
Yes! Just measure each room and hallway separately, add up the total square footage, and then apply your 10% waste factor at the very end.
The final price depends heavily on the wood species and its durability, often measured by the Janka hardness scale. Other factors include the plank width and the thickness of the wear layer for engineered wood.
