纸张尺寸参照表
A1:594mm×840mm
A2:420×594mm
A3:297×420mm
A4:210×297mm
A5:148×210mm
A6:105*148mm
B1:706×1000mm
B2:500×706mm
B3:353×500mm
B4:250×353mm
B5:176×250mm
依照长度和宽度不同分类，A4规格:21*29.7厘米 B4的规格:25*35.4，B5的规格:18.2*25.7
纸张的规格是指纸张制成后，经过修整切边，裁成一定的尺寸。过去是以多少"开"(例如8开或16开等)来表示纸张的大小，现在我采用国际标准，规定以 A0、A1、A2、B1、B2......等标记来表示纸张的幅面规格。标准规定纸张的幅宽(以X表示)和长度(以Y表示)的比例关系为X:Y=1:n 。
按照纸张幅面的基本面积，把幅面规格分为A系列、B系列和C系列，幅面规格为A0的幅面尺寸为841mm×1189mm，幅面面积为1平方米;B0的幅面 尺寸为1000mm×1414mm，幅面面积为2.5平方米;C0的幅
面尺寸为917mm×1279mm，幅面面积为2.25平方米;复印纸的幅面规格只 采用A系列和B系列。若将A0纸张沿长度方式对开成两等分，便成为A1规格，将A1纸张沿长度方向对开，便成为A2规格，如此对开至A8规格;B8纸张亦 按此法对开至B8规格。A0,A8和B0,B8的幅面尺寸见下表所列。其中A3、A4、A5、A6和B4、B5、B6等7种幅面规格为复印纸常用的规格。

举例说明:“A4”纸，就是将A型基本尺寸的纸折叠4次，所以一张A4纸的面积就是基本纸面积的2的4次方分之一，即1/16。其余依此类推。
一般打印纸就是采用复印纸,复印纸的分类是按大小分的,有几个标准:1、A型;2、B型;3、K型，K型纸就是我们常说的开型纸，只有在国内才有用K型纸 的。现在一般都用A型纸。不管A型B型，它的分类都是这样的，比如A5是A6的两倍，A4是A5的两倍，A3是A4的两倍，B4是B5的两倍B3是B4的 两倍，而K型的分类是把一张大的1K的纸分为两张为2K，把2K的纸分为一半为4K，把4K的分为一半为8K，把8K分为一半为16K，把16K分为一半 则为32K等。 还有办公用的专用打印纸，分类是按纸张的大小和层数分的，比如241-1，241-2，它们分别表示1层和2层的窄行打印纸，当然还有3
香港的天气层4层的;常用的宽行打印纸还有381-1，381-2等。
还有按纸张的厚度来分的，比如60g、70g、75g、85g、120g等等，是指在单位面积纸的重量是多重，因为纸的密度基本上是一样的，在单位面积纸 的重量越重，纸的厚度就越厚。比如一般速印机用的是40g左右的纸，而一体机用的是50-60g的纸，而复印机用的是70-85g的纸,打印机用的一般最 低不要使用低于60g厚的纸，否则就容易卡纸。 我国原来
的开本是由787×1092(mm)纸张来开的。由于787×1092(mm)纸张的开本是我国自行定义的，与国际标准不一致，因此是一种已经淘汰的非标准开本。

开数与开本的概念
通常把一张按国家标准分切好的平板原纸称为全开纸。在以不浪费纸
张、便于印刷和装订生产作业为前提下，把全开纸裁切成面积相等的若干小张称之为多少开数;将它们装订成册，则称为多少开本。 对一本书的正文而言，开数与开本的涵义相同，但以其封面和插页用纸的开数来说，因其面积不同，则其涵义不同。通常将单页出版物的大小，称为开张，如报纸，挂图等分为全张、对开、四开和八开等。 由于国际国内的纸张幅面有几个不同系列，因此虽然它们都被分切成同一开数，但其规格的大小却不一样。在实际生产中通常将幅面为787×1092(mm)或 31×43英寸的全张纸称之为正度纸;将幅面为889×1194(mm)或35×47英寸的全张纸称之为大度纸。由于787×1092(mm)纸张的开本 是我国自行定义的，与国际标准不一致，因此是一种需要逐步淘汰的非标准开本。
按照纸张幅面的基本面积，把幅面规格分为A系列、B系列和C系列，幅面规格为A0的幅面尺寸为841mm×1189mm，幅面面积为1平方米;B0的幅面 尺寸为1000mm×1414mm，幅面面积为2.5平方米;C0的幅面尺寸为917mm×1279mm，幅面面积为2.25平方米
未经裁切的的纸称为全张纸,将全张纸对折裁切后的幅面称为对开或半开;把对开纸再对折裁切后的幅面称为四开;把四开纸再对折裁切后的幅面称为八开，„„。 西安旅游路线
若纸张规格标记字母的前面加一个字母R(或S)时，是表示纸张没有切毛边，经过切边修整后，将减少到标准尺寸，例如RA4(或SA4)表示
不切边纸张的尺寸为240mm×330mm，经过切边修整后其尺寸为210mm×297mm。
1965 年国家标准规定图书杂志的开本为 A 、 B 、 C 三组， A 组是用原整张纸张为 880 毫米× 1230 毫米裁切的， B 组原纸张为 787 毫米× 1092 毫米， C 组原纸张为 695 毫米× 960 毫米。 1982 年， GB788 — 87 强调采用国际标准，目前正在推广中。新标准保留了旧标准中的符合国际标准的 A 系列，同时采用了国际标准 B 系列，淘汰了原标准中的 B 、 C 组两种开本。其目的是为了促进对外贸易和国际交流。我们平时复印时所说的 A4 、 B5 等就是国际标准。

Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementation of comprehensive strictly strategic plan, implementation in accordance with the rules and discipline to manage the party, stre
