Proportional Calculator allows you to scale an object proportionally, given the height and width of an object and one or more limiting factors ( square footage, max-height, or max-width).
If you need a calculator to find the square footage of an object measured in inches or feet; or someone needs to know how large or small an object will proportionally scale, Proportional Calculator is the right tool.
You can use different views; in the Basic view, enter the current height and width to get the square footage from inches or feet. Or, in the Advanced view, when entering the current measurement and width along with either max-height, max-width, or max square footage, Proportional Calculator will return the largest possible size the object can be while meeting the given parameters.
Proportional Calculator Features:
Can calculate square footage
Can calculate proportional scale given max square footage
