This online tool calculates the diagonal depth of any piece of furniture, aiding in space planning and furniture placement. Understanding the diagonal depth is essential when moving furniture through doors, planning room layouts, or purchasing custom furniture covers.

## Formula of Furniture Diagonal Depth Calculator

To find the diagonal depth of a piece of furniture, use the following formula:

Where:

**Height**is the vertical dimension of the furniture.**Depth**is the horizontal dimension from front to back.

**Steps to Calculate:**

- Measure the height of the furniture from the bottom to the top.
- Measure the depth of the furniture from the front edge to the back edge.
- Square both the height and the depth measurements.
- Add the squared height and squared depth.
- Take the square root of the sum to get the diagonal depth.

## Table of Common Furniture Dimensions and Their Diagonal Depths

For convenience, below is a table with common furniture dimensions and their respective diagonal depths. This table serves as a quick reference to avoid manual calculations each time.

Furniture Type | Height (in) | Depth (in) | Diagonal Depth (in) |
---|---|---|---|

Sofa | 34 | 38 | 51 |

Coffee Table | 20 | 30 | 36 |

Bookshelf | 72 | 15 | 73 |

Dresser | 48 | 20 | 52 |

## Example of Furniture Diagonal Depth Calculator

Consider a sofa with a height of 34 inches and a depth of 38 inches. Using our formula:

Diagonal Depth = √(34² + 38²) = √(1156 + 1444) = √2600 ≈ 51 inches.

This calculation shows that the sofa's diagonal depth is approximately 51 inches.

## Most Common FAQs

**Q1: Why is diagonal depth important for furniture?**A1: Diagonal depth helps determine if a piece of furniture can fit through doorways, corridors, and other tight spaces without the need to tilt it significantly.

**Q2: How can I measure furniture dimensions accurately at home?**A2: Use a reliable tape measure, measure from the widest points for both height and depth, and ensure the tape is straight and tight during measurements.

**Q3: Are there any mobile apps available for furniture measurement calculations?**A3: Yes, several apps are available that can help in measuring and calculating the dimensions of furniture, with some even offering augmented reality to visualize furniture in your space.
