Also known as blueprints

Can plans be the same size as the project? What do you do?

Draw to scale!

Reading Scale Think about a ruler

How do you use it?

Think of how you break down an inch

Reading Scale We have a building that is 100 feet long. How big of a piece of paper would we need?

Full size 100 feet

1 inch = 1 foot 100 inches

½ inch = 1 foot 50 inches

¼ inch = 1 foot 25 inches

1/8 inch = 1 foot 12.5 inches

Reading Scale Difficult to always try to measure with a ruler

and convert Architect’s Scale

Special type of ruler to help you make the conversions in one easy measurement

Reading Scale Scale has numerous sides with numerous

scales Scale marked on the side

Align the number on the scale with the scale your drawing is

Numbers printed will then help you determine feet

Reading Scale Numbers tell you whole feet Not everything is in whole feet

Use the small hashes at the end Be sure you know the division!

Look at number of marks See the relationship to 1 foot

Reading Scale ¼ scale

Each hash mark = 1 inch 12 hash marks 12 inches in a foot 12 ÷ 12 = 1

Reading Scale 1/8 scale

Each hash mark = 2 inches 6 hash marks 12 inches in a foot 12 ÷ 6 = 2
