Can I use this calculator if only one dimension of the new rectangle is known?

The linear scale factor is found by dividing the new width by the original width or the new length by the original length; the area scale factor is the square of the linear scale factor, representing how surface area changes under proportional resizing.

What does the area scale factor represent?

The area scale factor represents the multiplicative change in total surface area when a rectangle is resized proportionally; it is calculated by squaring the linear scale factor.

Is the scale factor the same if I swap which rectangle is source and which is target?

No, reversing the source and target rectangles inverts the scale factor (e.g., a factor of 2 becomes 0.5), reflecting the direction of the resize operation.

About this tool

What Rectangle Scale Factor Calculator does

This calculator determines the linear and area scale factors between two rectangles. Users input the width and length of a source rectangle and the width and length of a target rectangle; the tool then computes the ratio of corresponding sides (linear scale factor) and the square of that ratio (area scale factor). The output provides both the multiplicative factor for resizing lengths and the resulting change in total surface area, making it useful for comparing proportional dimensions in two-dimensional space.
