3. Type Measurement Type Sizes are used to distinguish different measures of printed type. Type Sizes are used to distinguish different measures of printed type. English-speaking countries use the point system which consists of points and picas. English-speaking countries use the point system which consists of points and picas.

4. Type Measurement The point measures approximately 1/72” (0.0138”) The point measures approximately 1/72” (0.0138”) The pica measures approximately 1/6”. Twelve points equals a pica, and six picas equal approximately one inch (0.996”) The pica measures approximately 1/6”. Twelve points equals a pica, and six picas equal approximately one inch (0.996”)

5. Type Measurement A line gauge is an instrument used to measure type sizes and line lengths in picas or inches. A line gauge is an instrument used to measure type sizes and line lengths in picas or inches. Line gauges typically measure up to 72 picas (approximately 12”). Line gauges typically measure up to 72 picas (approximately 12”). One side of the gauge is marked in inches and the other side is marked in picas and nonpareils (units equal to one-half pica). One side of the gauge is marked in inches and the other side is marked in picas and nonpareils (units equal to one-half pica).

6. Measuring Point Size Point size includes a small amount of white space above and below the letter for line spacing. Point size includes a small amount of white space above and below the letter for line spacing. An E gauge can determine point size by placing the gauge flat over a line of type and matching the letter “E” closest in size to the letter in the line. An E gauge can determine point size by placing the gauge flat over a line of type and matching the letter “E” closest in size to the letter in the line. Leading is the vertical space between lines of type and is measured in points Leading is the vertical space between lines of type and is measured in points

7. Measuring Paper Sizes Paper sizes are designated in length and width dimensions. Paper sizes are designated in length and width dimensions. Paper for business is usually packaged in reams, which consist of 500 sheets. Paper for business is usually packaged in reams, which consist of 500 sheets. Different types of paper are known as grades and are classified with a basic size. Different types of paper are known as grades and are classified with a basic size. Basis weight of paper is a measure of the number of pounds in a ream of paper cut to its basic size Basis weight of paper is a measure of the number of pounds in a ream of paper cut to its basic size

8. Measuring Paper Sizes Some commonly used grades of paper, and their basic sizes: Some commonly used grades of paper, and their basic sizes: Bond, 17” x 22” Bond, 17” x 22” Book, 25” x 38” Book, 25” x 38” Offset, 25” x 38” Offset, 25” x 38” Cover, 20” x 26” Cover, 20” x 26” Text, 25” x 38” Text, 25” x 38”

9. ISO Sizes ISO – International Organization for Standardization. ISO – International Organization for Standardization. The sizes, known as the ISO series, are given in both SI Metric units (millimeters) and US Conventional units (inches). The sizes, known as the ISO series, are given in both SI Metric units (millimeters) and US Conventional units (inches).

10. ISO Sizes ISO sizes are commonly grouped into three series. ISO sizes are commonly grouped into three series. A-series sizes are used for general printing requirements. A-series sizes are used for general printing requirements. B-series sizes are used for posters. B-series sizes are used for posters. C-series sizes are used for postcards, folders and envelopes. C-series sizes are used for postcards, folders and envelopes.

12. Image Measurement Resolution describes the visual quality of an image. Resolution describes the visual quality of an image. The resolution of a printed image is measured in dots per inch (dpi) or pixels (picture elements). The resolution of a printed image is measured in dots per inch (dpi) or pixels (picture elements). A pixel is a tiny rectangle that is only visible as a dot on a computer screen. A pixel is a tiny rectangle that is only visible as a dot on a computer screen.
