Government College of Engineering and Leather Technology

The Government College of Engineering and Leather Technology is one of the pioneering engineering colleges of our country, established by the British Raj on the 11th day of March in the year 1919, just after World War–I. The historical perspective has been dealt with in the History section of this website. This government institute is under the administrative control of the Directorate of Technical Education West Bengal and the Department of Higher Education of the Government of West Bengal.

Since its inception, its focus has been on teaching and research in leather technology, footwear, and leather goods making, providing assistance to industries, and also providing training and organizing seminars and workshops to disseminate the knowledge to the stakeholder. There has been a gradual change in the morphology of this college since 2000 when a B. Tech. course in information technology was offered by this institute. In 2001, another B. Tech. course in computer science and engineering was offered. Keeping pace with horizontal expansion, in 2005 we looked into vertical expansion by introducing the M. Tech. program in Leather Technology.

11th March 1919

The Government College of Engineering and Leather Technology (GCELT) was originally started under the name ‘Calcutta Research Tannery’ in the year 1919 on the recommendation of the Munitions Board set up by the Government of India immediately after the First World War. The college originally was situated on Canal South Road, Pagladanga, P.O. Tangra, Calcutta – 700015.

In the year 1926, ‘Calcutta Research Tannery’ was renamed ‘Bengal Tanning Institute’ in the ambit of the Department of commerce and Industry.

August 1955

In August 1955 this college was affiliated with the University of Calcutta for imparting training in B. Sc. (Tech) course in Leather Technology and it has been recognized as a professional college under the University of Calcutta.

In the year 1958 ‘Bengal Tanning Institute’ was renamed ‘COLLEGE OF LEATHER TECHNOLOGY’ (CLT).

A change in the department from the Commerce and Industry so far to the Department of Higher Education took place in the year 1968.

The college undergoes a paradigm shift with the change in location from Pagladanga to the prime location of Salt Lake on E. M. By-Pass

Information Technology was introduced as B-Tech Course.

Computer Science Engineering was introduced as B-Tech Course.

M. Tech program in Leather Technology as a feather on the cap of vertical expansion and affiliating umbrella also changed to ‘The West Bengal University of Technology’ from ‘The University of Calcutta’.

A clear site about standard paper sizes. Sponsored by inXpection.com, a leading China 3rd party inspection company.

Paper Sizes Overview

It might be confusing that, when you find it for the first time that a Legal Size Paper and a Standard Size Paper are actually not the same thing- because it is bit complicated to explain how to identify a Legal thing from a Standard one, if take it literally. In fact, the former is in scope of US paper sizes, while the later normally means ISO standard paper sizes. Other questions about may puzzle you too when encounter in work and life, for example, if you are American, what is A4 paper size , the most widely used paper size in the world except North America? And A3 size , A5 size ? Or, if you are not an American,then what is Letter paper size or Tabloid paper size ?

As mentioned above, standards of paper size vary in different areas of the world. ISO size standards are accepted by the most Countries, while US size standards are mainly used in U.S., Canada and a few other non-American country like the Philippines. Below are quick links for the most of information involved in this site, more can be found from the top and side menus, you can also use the search box to look for what you want about.

You can also search more information you want using the search box, or tell us if there are missing or inaccurate details. Information will be added constantly in response to your request.

ISO Paper Sizes

When we talk about ISO paper size, we normally mean the ISO 216 standard , which includes ISO A series sizes and ISO B series sizes , specifies the trimmed sizes of writing paper and certain classes of printed matter. There are also C series sizes but specified by ISO 269 standard. Most ISO standard sizes are all based on the √2 ratio, which means, the length of a sheet is equal to its width times 1.4142.

There is also ISO 217 standard, which specifies untrimmed paper sizes- RA and SRA .

A Series Sizes

The ISO A series is the most widely used paper measurement standard in the world, it has been spreading very fast after it was created in 1975. A0 is the the largest size in this series, numbers last to A1 , A2 , A3 , A4 and so on, but for A sizes after A8, there are not a lot of operability in exact work because of the really too small size.

• S (A0) = Exactly 1 square meter ( S means total area )
• The length of the sheet is equal to its width times 1.4142.
• An is devided into two equal parts of A(n-1) size, so
• S (An) = 2 x S [A(n-1)]

>> A Series Paper Sizes – A0, A1, A2, A3, A4, A5, A6, A7, A8

B Series Sizes

The ISO B sizes was introduced in case of the A series isn’t suitable, it is normally used in commercial printing work like for posters, also to fit for some professional printers for magazines and maps. Its unique usage makes B series  not so popular as A series. Also, different from A0 measures 1 m² in area, B0 starts from a width of 1 meter. And as mentioned, ISO ratio logic applies to B series too. Same as A series, B sizes after B8 don’t have a lot of operability in exact work.

So, rules are here:

• Width (B0) =  Exactly 1 meter
• Bn is divided into two equal parts of B(n-1) size, so
• S (Bn) = 2 x S [B(n-1)]  ( S means total area )

>> B Series Paper Sizes – B0, B1, B2, B3, B4, B5, B6, B7, B8  

C Envelope Sizes

The ISO C Series is used for envelopes fitting the dimension of A series paper of same size number, and slightly larger than it. That’s why it is also called C envelope sizes, and used right in the areas of the world where A series paper   covers.

• ISO ratio logic applies, the length of the sheet is equal to its width times 1.4142.
• S (Cn) = 2 x S [C(n-1)]  ( S means total area )

>> C Series Paper Sizes (C Envelope Sizes) – C0, C1, C2, C3, C4, C5, C6, C7, C8

D Series Sizes (Non-ANSI D Size Paper)

ISO D series is not used widely, we have tried to search for more information about this series for a while but there is rare found. It is said that D series has same usage as C series but fits for B series as envelope use,  but we think it is not correct because a C(n) sheet is much smaller than a B(n) sheet, how can it hold a flat sheet bigger than itself? It is much more close to fit a B(n-1) sheet. Please tell us if you know about it, thanks.

RA sizes and SRA sizes

When representing sizes for paper, RA stands for “ RAW format A” , and the word SRA for “ Supplementary-RAW format A” , thus they are slightly larger than the standard A sizes. Defined by ISO 217 standard, RA and SRA Series are oversized and are used by printers for metric sizes. Please find information about RA and SRA sizes in A paper sizes .

American Paper Sizes

The US and Canada primarily use a different sizes system for paper, compared to the rest of the world. They use unique words, such as, Letter, Legal, Executive, and Tabloid/Ledger as the most common paper size terms. US sizes are the only ones included in CSS (Cascading Style Sheets), which is use for website construction. Letter paper size is the most popular size used in the US; while Legal size paper , called foolscap size paper too, also used in the UK, and Commonwealth Countries .

Besides, there are ANSI standard and Arch standard in US. The ANSI standard, which has sizes from A to E, was established in 1995 and created a set of sizes based on shared dimensions. The Arch sizes is from A to E too. ANSI B+ and Arch E1, E2, E3 were then added as extensions to refine the standards.

Paper Sizes in Other Countries, and Sizes For Certain Usage

Beside the size standards we listed above, there are other different sizes of paper used in other countries. There are also sizes for certain use, for example, Poster , Postcard , Picture , Business Card , Envelope , etc. Hope you can find all the related information you want in this website, or tell us if you can’t.
