Which dimension is listed first

Dimensions in blueprints represent the size of an object in two- or three-dimensional space. For example, a dimension of a rectangular room on a blueprint, 14' 11" X 13' 10" equates to a room size of 14 feet, inches wide by 13 feet, inches long.

Dimensions are expressed as width by length by height or depth in three-dimensional space. A three-dimensional desk for example, may be expressed as 25" X 82" X 39" which means the desk is 25 inches wide by 82 inches long and 39 inches tall. A window dimension on blueprints is treated as two-dimensional space. For example, a window that is 24 inches wide by 30 inches tall would be written as 24" X 30".

In the manufacturing industry, this standard window size is referred to as a or 2 feet by 3 feet. Special Offers. Monthly Specials, New Products, Overstock. About Us. How do you measure a box? The first dimension to measure is length. Length is always the longest side of the box that has a flap. The next dimension is width. The width side also has a flap, but is always the side shorter than the length.

Measure the height of the package. Height is the only dimension without a flap. The length and width of an object or space are used to determine an object's area. Additionally, these measurements can be used to measure the perimeter or distance around the edge of the object.

If there is a third measurement depth , the three are used to determine the volume of an object. Labeling the measurements clearly is important so others can get a clear picture of the size and shape of an object. Though there are no strict rules in how to express measurements, there are a few guidelines that people can follow. Length vs. Width When looking at a two-dimensional object, it might be difficult to decide which side or measurement refers to the length and which side refers to width.

If a person is looking at a rectangular shape, the length should refer to the longest side. One can equate length with the word "long" in this instance. Conversely, width would refer to the shorter side and is used to describe how wide the rectangle is. Height In terms of dimensions of an object, the terms "length" and "height" might be used interchangeably.

Both terms refer to the longest side of the shape.
