The scale allows us to understand the relation between the size of real objects and their size on architectural drawings. The scale helps architects accurately represent the interior and exterior of building in smaller and more practical size that will fit on paper. The architectural scale converter on our website has a wide range of usage. It can help you with calculations necessary for drafting floor plans, sectional views, location plans, or construction details.

1/4˝ = 1´-0˝ is one of the architect scales used for drawing buildings and structures. This scale shrinks everything so if there is something in the real world with a length of 1 foot then it will have only 1/4 inch in the architectural drawing.

The scale includes 3x values. 1.) Length in the drawing 2.) Colon “:“ or equals “=“ 3.) Length of the real object. If you have 1:10 scale then 1 (unit) in the drawing is 10 (units) in the real world.

1 : 10

100 cm : 10

Win rate = 50 / 100

Result = 10 cm

100 cm : 10

Win rate = 50 / 100

Result = 10 cm

1/4 inch = 1 feet

16 x 1/4 inches = 16 x 1 feet

4 inches = 16 feet

16 x 1/4 inches = 16 x 1 feet

4 inches = 16 feet

Scales on floor plans usually relate to inches or millimeters. If you are located in the USA you will be working in the imperial system (in, ft, yd, mi, h, ch, lea, fur, th). If you are in Europe or Australia, it will be the metric system (mm, cm, dm, m, km). Architects in Canada work with both of these systems. If you look at the dimensions in the floor plan, you will immediately know if it's using the metric or imperial system.

Architectural drawings include floor plans, sections, and elevation views. These types of drawings are representing building design and construction. Horizontal views of buildings are most commonly seen on architectural plan sheets.

Architectural plans show construction workers building details so they can know where to place doors, how many floors will have the building, or what materials they have to use. The construction stage of a new building is not possible without proper technical drawings.

Representing reality on the piece of paper is only possible through scaling. It's practical to change actual measurements of objects so your architectural and technical drawings fit on the page or your models fit on the table. You would need a lot of paper to draw 10 meters line, but if you use 1:100 scale then you have to draw only 10 centimeters. It's pretty smart, don't you think? Although, modern CAD software can work even with 1:1 scales.

The engineering scale is more accurate than the architect’s scale and uses a decimal scaling scheme while an architect's scale is using fractional scaling.

Both engineering scale and architect’s scale are meant for drafting plans or obtaining measurements from existing technical drawings, or drawings of buildings, structures, and exterior / interior rooms.

The base measuring unit of the metric scale is millimeter and 1:1 represents full size on the metric scale while 1:2 is half scale. Half scale means that one unit on the drawing is equal to two units on the actual object.

Architect scales are converting inches into feet. 1/4 inch = 1 foot means that 0.25 inch in the drawing is 1 foot in reality.

The metric scale can be read from left to right, the same as the engineering scale. An architect's scale, on the other hand, is possible to read from both sides.
