Lowes Soffit Vent Calculator
Lowes soffit vents are crucial for maintaining proper airflow and preventing moisture buildup in your attic. Our calculator helps you determine the right vent size for your needs.
- Enter the length and width of your soffit area in inches.
- Select the vent type: Standard or Low Profile.
- Click ‘Calculate’.
The calculator uses the following formula to determine the required vent area:
Vent Area = (Length * Width) / 144
The results are then adjusted based on the selected vent type.
| Attic Size (sq ft) | Vent Area (sq in) |
|---|---|
| 1000 | 1000 |
| 1500 | 1500 |
| 2000 | 2000 |
| Vent Size (in) | Standard (sq in) | Low Profile (sq in) |
|---|---|---|
| 10×14 | 10 | 7.5 |
| 12×16 | 19.2 | 12 |
| 14×24 | 33.6 | 22.5 |
- Always round up to the nearest whole number when selecting a vent size.
- Consider installing a combination of intake and exhaust vents for optimal airflow.
