What is the standard GSM used by most Indian print shops?

Most print shops use 70 or 75 GSM for routine black-and-white printing. Printster offers a range of options from 70 GSM upwards so you can choose the weight that suits your document.

Does higher GSM paper cost more?

Yes, heavier paper costs more per sheet because it uses more material. The price difference between 75 GSM and 90 GSM is modest; jumping to 120 GSM adds more noticeably to the total cost.

What GSM is best for a thesis?

90–100 GSM for the interior pages is the most common choice — it feels professional, has minimal show-through and is what most examiners expect. For the cover, 170–200 GSM or a laminated cover sheet is standard.

Will I see through 75 GSM paper when printing double-sided?

With B&W text at normal coverage, show-through on 75 GSM is minimal and acceptable. For heavy colour coverage or dense graphics, 90 GSM eliminates the issue.

What GSM paper should I use for a presentation?

For a wiro or spiral-bound colour presentation, 90–100 GSM interior pages and a 200–250 GSM colour cover gives a professional feel. If cost is less of a concern, 120 GSM interior pages elevate the quality further.

Can I mix different GSM papers in one document?

You can specify a heavier GSM for the cover and a lighter GSM for interior pages — this is the standard approach. Mixing GSM within the interior pages is not a standard configuration.

Paper GSM Guide

GSM stands for grams per square metre — it measures paper weight and thickness. Higher GSM means thicker, sturdier paper. For everyday documents and notes, 70–80 GSM is standard. For reports and theses, 90–100 GSM gives a better feel. Cover pages typically use 170–300 GSM.

GSM is the most important paper specification to understand before placing a print order. It tells you how thick and substantial the paper will feel, how well it resists show-through (where text from one side is visible on the other), and how the finished document will hold up to use. In India, most photocopying and routine document printing is done on 70 or 75 GSM paper — it is cheap, light and adequate for daily use. But when you are printing a thesis you have spent years writing, a presentation that will sit in front of a client, or notes you plan to use for months of study, the paper weight makes a real difference to the quality and durability of the finished product. This guide explains the GSM scale, recommends the right weight for common print jobs, and helps you decide which option gives the best value for your specific use case.

The GSM Scale Explained

Paper GSM values commonly used in printing range from around 60 GSM (very thin, lightweight) to 350 GSM (thick card stock used for business cards or greeting cards). Here is how the most common weights in document printing compare:

GSM	Character	Common Use
60–70 GSM	Very light, semi-transparent	Newspaper, flyers, cheap handouts
75–80 GSM	Standard office paper	Everyday printing, notes, drafts
90–100 GSM	Slightly heavier, minimal show-through	Reports, study notes, thesis interior
120 GSM	Noticeably thick, no show-through	Premium reports, presentation interiors
170–200 GSM	Card-like weight	Cover pages, dividers
250–300 GSM	Thick card	Hardcover covers, heavy dividers

Which GSM Should You Choose?

70–80 GSM — bulk printing on a budget: This is the right choice when volume and cost are the priority — coaching notes, rough draft copies, large study packs. Show-through is minimal for B&W text but visible if ink coverage is high.

90–100 GSM — the quality sweet spot: One step up from standard office paper, 90–100 GSM gives a noticeably more substantial feel without a significant price increase. Highly recommended for thesis interiors, project reports and anything you plan to keep.

120 GSM — premium document feel: Documents on 120 GSM feel crisp and professional. Ideal for client-facing reports, business proposals and portfolios. Pages have zero show-through and hold colour well.

170–300 GSM — cover pages only: This weight range is used exclusively for covers. A 170–200 GSM cover on a spiral or wiro-bound document is durable and holds its shape. Hardcover and perfect-bound books use a printed cover mounted on board rather than loose paper.

Does GSM Affect Binding?

Yes, in two ways. First, thicker paper means more sheets are needed to fill the same document (a 100-page document on 120 GSM will be slightly thicker than on 80 GSM). Second, very thick interior paper (above 120 GSM) can make folding and binding more difficult for saddle-stitch and wiro binding. For most documents, 80–100 GSM interior pages bind without any issues.

GSM and Colour Printing

For colour pages, GSM matters more. Ink applied to thinner paper can cause slight buckling, especially in areas of heavy ink coverage. 90 GSM or above is recommended for colour interior pages. High-quality colour presentations or portfolios benefit from 120 GSM or a coated (glossy) paper stock.
