This calculator requires the use of Javascript enabled and capable browsers. This script creates a calculated table of scaled size objects from measured real life size objects, based on the scale fraction, or the type of construction model, in order to create a more accurate layout or display. This calculator may be useful in the construction of Christmas villages, scale towns, dollhouses, playhouses, treehouses architectural depictions or similar projects. Area distances are the most difficult scale to achieve because of physical space limitations of most displays. These scales vary somewhat worldwide and from manufacturer to manufacturer or creator to creator; however these are the generally accepted sizes and conversions. Calculations can be made in an automated fashion by selecting the scale of your choice (current, generally standard scales listed only), entering the Real Life Size in feet and clicking on Calculate; the default is 87.1 for HO scale projects, the most popular scale. The scale fraction will show in the scale fraction box after clicking on Calculate. To manually process the calculation, choose Other for the scale; enter the scale fraction of your choice directly in the scale fraction box. If the size scale is 1:64, you should enter the 64 in the box. Enter the Real Life Size in feet. For instance a wall is 8 feet high; enter 8. Then click on Calculate. This will work with any scale size relationship. To do any additional calculations, click on Clear Values prior to entering any new values.
