Dimensions Calculator
Calculate area, volume, and dimensions with precision. Convert between units and visualize your measurements instantly.
Area (2D)
Surface measurement
A = L × W
Volume (3D)
Space occupancy
V = L × W × H
Area
The measure of surface coverage
Area = Length × Width
Volume
The measure of 3D space occupied
Volume = Length × Width × Height
Length Width Height Dimensions Calculator – Easy Online Guide
When you need to measure something, you often hear the words length, width, and height. These three numbers tell you the dimensions of any object — whether it’s a box, a room, or even furniture. With a length width height dimensions calculator, you can quickly find area, volume, or even the right size for shipping and packaging.
Formula: Length × Width × Height
Uses: Area, volume, cubic feet, shipping size, furniture fit
Units: Inches, feet, square feet, square meters, cubic meters
Applications: Packaging, Amazon FBA, UPS/DHL shipping, room design, moving, CAD, 3D printing
Format: Always written as L × W × H
Why Use a Dimensions Calculator?
A dimensions calculator saves time and reduces errors. Instead of guessing, you can plug in numbers and instantly see results. This is useful for:
- Shipping boxes with UPS, FedEx, or DHL
- Amazon FBA dimensions requirements for sellers
- Planning furniture placement in a room
- Finding the cubic feet for storage or moving
- Designing with CAD tools or 3D printing
Basic Formulas for Dimensions
- Length x Width x Height = Area (for flat surfaces)
- Length x Width x Height = Volume (for 3D objects like boxes)
- Area to length and width calculator square meters helps convert area into exact measurements.
Example: If a box is 10 inches long, 5 inches wide, and 4 inches high, the volume is:
10 × 5 × 4 = 200 cubic inches
Dimensions Table (Quick Conversion)
| Measurement | Formula | Example | Result |
|---|---|---|---|
| Area (flat) | Length × Width | 10 ft × 5 ft | 50 sq. ft. |
| Volume (3D) | Length × Width × Height | 10 in × 5 in × 4 in | 200 cubic in |
| Cubic Feet | (L × W × H) ÷ 1728 | 24 in × 12 in × 12 in | 2 cu. ft. |
| Square Meters | (L × W) ÷ 10.764 | 10 ft × 5 ft | 4.64 m² |
Online Dimension Tools
With an online length, width height calculator, you can measure in:
- Inches → length width height dimensions calculator inches
- Feet → length width height dimensions calculator in feet
- Square feet → length width height dimensions calculator square feet
- Square meters → length width height dimensions calculator square meters
Many calculators even act as a dimensional weight calculator for shipping costs.
How to Write Dimensions Correctly
When you see product sizes, they usually appear as L × W × H. Here’s how it works:
- Length = the longest side
- Width = the side at a right angle to length
- Height (or depth) = how tall the object is
Example: A package listed as 20 × 10 × 5 means 20 inches long, 10 inches wide, 5 inches high.
This is the same format used by shipping carriers, furniture makers, and online stores.
