What is the first step in calculating baseboard gross linear feet?

The first step in calculating baseboard gross linear feet is to calculate the total baseboard length before deductions. This step involves assessing the full length of the walls where baseboard will be installed, without yet considering any interruptions, such as doorways, windows, or built-ins that would reduce the amount of baseboard needed.

By establishing this total length first, you create a baseline measurement that is essential for subsequent adjustments. Once you have the total length, you can proceed to account for any interruptions and adjust for double counting. This foundational step is critical as it ensures all potential areas for baseboard installation are initially taken into consideration, allowing for a comprehensive assessment of the materials needed for the project.
