Here are the size specifications of some books:

extended data

1. According to the materials used, it can be divided into two types: ridge same material and ridge different material

the spine is made of the same material, that is, the spine and the cover and back cover are made of the same material. There are square ridge and round ridge. Hardcover fabrics are mostly paper, fabric, lacquer paper, lacquer cloth, etc., which are generally equipped with protective covers. However, there is a kind of book with the title and pattern printed on the whole paper and pasted on the cardboard by pressing film. Most of these books are square ridges without protective cover

(1) different materials on the spine surface:

that is, the spine and cover are made of different materials. Usually, the fabric is used as the spine and the paper is pasted on the hardboard as the cover. This form is generally round spine without protective seal

C (floating mouth): 2 ~ 3mmf (wrapping mouth): 13 ~ 15mm

e (Book slot width): 6 ~ 7mmh (paper and ridge interface): 6 ~ 7mm

k (cloth waist and paper edge width): 3 ~ 5mmg (middle seam width): D + 2E

(2) ridge same material:

A (cloth width): H + 2C + 2F

b (cloth length): 2S + D + 2E + 2C + 2F
/P>

A (cardboard length) The <

2 Calculation method of spine arc length:

no ridge (only round, no ridge) d = (130 ° × π × Book thickness /2) /180 °

ridged (rounded, ridged) d = [130 ° × π × (Book thickness + 2 paperboard thickness) /2] /180 °

3. The materials and dimensions inside the spine are as follows: gauze length: h-20

gauze width: D + 40

the plug cloth length is equal to the ridge arc length

the ribbon length is equivalent to the diagonal length of the book block

4 Size of protective seal:

A (width of protective seal): H + 2C

Q (length of protective seal): b-2f + 2R

R is the flange of protective seal, which is generally more than 30mm. According to the size of folio, the flange can be made larger without wasting paper and convenient for printing

the dimensions listed above are all the dimensions after cutting. The notch should be considered when designing the cover and cover, that is, 3mm notch should be left in the top, bottom, left and right during the design of the drawing

example: 120 folio, finished product size 185 × 208, 112 sides of text, 8 sides of front and rear ring lining, and both text and ring lining are printed with 80g /m2 double offset paper. For square ridge hardcover, the ridge is sealed with 120g /m2 coated paper, pressed film afte
r printing and pasted with hard shell. Use 1.5mm thick cardboard. How wide should the designer design the cover

5. The square spine hardcover has two kinds of full cloth surface and full paper surface. The material size is the same. It is estimated that the thickness of the spine is 7mm

A (paper width): H + 36 = 208 + 36 = 244 (mm)

b (paper length): 2S + D + 2 × 1.5+48=2 × 185 + 7 + 3 + 48 = 428

A (paperboard length): H + 6 = 208 + 6 = 214 (mm)

b (paperboard width): S-4 = 185-4 = 181 (mm)

cover designers can visit (244 + 6) × (428 + 6) i.e. 252 × 434 design on paper; When designing the pattern, it should be considered to remove the wrapping size to ensure the correct position of the pattern

example: 216 folio, finished product size 185 × 260, 600 sides of the text, 80g /m2 double tape, 120g /m2 double tape for the front and rear ring linings, the same material for the back cover, round ridge hardcover, round ridge, 2mm thick paperboard, and the thickness of the spine is calculated to be 34mm. Calculate the size of the cover and cover of the book

A (cloth width): H + 36 = 260 + 36 = 296 (mm)

b (cloth length): 2S + D + 48 = 370 + 43 + 48 = 461 (mm)

d = [130 ° × π × Length of paper cover
<2R + 266> (P <2R + 266)> (P <2R + 2x)>> length of paper cover <264 (P + 6)> (P <2R + 2x)> (P <2R + 2x)> (P <2R + 266)> (P <2R + 2x)>> length of paper cover <264> (P <2R + 2x)> (P <2R + 2x)>> width of paper cover <264> (P + 2x)> (P <2x)> <2x)> (P <2x)> (P = 260)> (P + 2x)> (P <2x)> <2x)> (P <2x)> (P <2x)> (P <266)> (P

cover designers can × (437 + 2R) the sealing design shall be carried out in the paper

example: 332 folio, finished product size is 130 × 185, 636 sides of the text, printed on 52g /m2 convex board paper, 12 inscriptions on the front and back lining and title page, and 80g /m2 double offset paper. The materials used for the ridge surface are different. The cover is paper surface, cloth waist, 2mm thick cardboard and round ridge

it is estimated that the thickness of the spine is 26mm. Calculate how wide the cover should be designed

A (paper length): H + 36 = 185 + 36 = 221 (mm)

m (paper width): S + 8 = 130 + 8 = 138 (mm)

A (cloth waist length): 221 (mm)

L (cloth waist width): [130 ° × π × (26 + 4) /2] /180 ° + 36 = 70 (mm)

A (mid seam length): H + 6 = 191 (mm)

d (mid seam width): [130 ° × π × (26 + 4) /2] /180 ° = 34 (mm)

therefore: the designer can × 144 design on paper

through the analysis of typical examples, binding designers are required to master the knowledge of the type, specification, performance and price of paper materials, the calculation method of book cost and labor price, printing technology and operation process; Only in this way can we avoid unnecessary economic losses in each link according to the nature of book content and Reader level, combined with material and technical conditions, and under the design principles of practicality, beauty and economy
