How to Choose Cotton Fabric: GSM, Width & Construction Explained

How to Choose Cotton Fabric: GSM, Width & Construction Explained

Choosing fabric sounds simple until you start comparing actual specifications. Two fabrics may look similar in a photograph but feel completely different in your hands. One may be lightweight and easy to drape, while another may have more body and structure. Even fabrics with the same GSM can behave differently because their yarns, construction and finishing are not the same.

When sourcing fabric for a clothing brand, bag collection or home textile business, it helps to understand a few basics before placing an order.

At BOHOBLOCKPRINTED, we believe that the best fabric is the one that suits the finished product. Instead of choosing only by colour or price, it is worth looking at GSM, width, construction and fibre composition together.

This guide explains these details in straightforward terms so you can make a more informed decision when buying fabric.

1. Start With the Product You Want to Make

Before comparing fabric specifications, think about the finished product.

A lightweight shirt, a structured tote bag and a tablecloth do not necessarily need the same type of fabric. Each product has different requirements for weight, drape, texture, durability and care.

For example, a fabric selected for a relaxed garment may need to feel soft and move easily. A material for a structured bag may need more body. For curtains or table linen, width and the way the fabric falls can be especially important.

Write down the main requirements of your product before approaching a supplier. This makes it easier to narrow down the available options.

2. Understand GSM Before Choosing Fabric

GSM stands for grams per square metre. It describes the weight of a fabric over a standard area.

Buyers often use GSM to compare fabrics, but it is important to remember that GSM does not tell the whole story. Two fabrics with the same weight may have different thicknesses, textures, flexibility and strength.

Here is a simple way to think about fabric weight:

Lower GSM: Often worth considering when a project calls for a lighter material. The exact feel depends on the construction and fibre content.

Medium GSM: Can offer a balance between weight and flexibility, depending on the fabric type and intended use.

Higher GSM: May provide more body and a substantial feel, although it can also make a fabric less flexible or more difficult to sew.

These are general guidelines, not fixed rules. A fabric should always be assessed according to its actual construction and intended application.

When requesting a quotation, ask for the stated GSM and confirm whether it refers to the finished fabric or another production stage.

3. Why Fabric Width Matters

Fabric width affects how efficiently you can cut your product pieces. Choosing the wrong width can lead to extra seams, material waste or changes to your production layout.

For example, a small accessory may work comfortably with a standard-width fabric. A large tablecloth, curtain panel or bedding component may need a wider option to achieve the desired dimensions with fewer joins.

Our listed fabric specifications include a range of widths, from narrower options for specific constructions to wider options reaching 120 inches and beyond in selected fabrics.

The important point is that width depends on the exact construction. You should not assume that every fabric type is available in every width.

Before ordering, confirm the usable width, check the selvedges and allow for any shrinkage or finishing changes. If you have a cutting pattern, sharing its dimensions with your supplier can help when comparing suitable options.

4. Learn the Difference Between Fabric Constructions

The construction influences the appearance, texture and handling of a fabric. Different constructions serve different purposes, which is why the fabric name alone is not enough to make a buying decision.

Plain and Sheeting Fabric

Plain or sheeting fabrics are useful categories to consider when looking for a straightforward woven surface. The right specification depends on the product, required weight and finishing.

Dobby Fabric

Dobby fabrics are woven using a technique that can create small geometric or textured patterns in the cloth. They may be worth considering when a design calls for more surface interest than a simple, uniform weave.

Drill Fabric

Drill is commonly associated with a diagonal twill structure and is often considered for products that need a more substantial fabric. The actual weight and performance depend on the selected construction.

Twill Fabric

Twill is recognised by its diagonal weave pattern. Twill fabrics come in different weights and fibre compositions, so check the exact specification rather than assuming all twills have the same feel.

Poplin Fabric

Poplin is often selected for a relatively smooth, closely woven surface. Its suitability depends on the construction, weight, fibre content and final use.

Slub Fabric

Slub fabrics have a textured appearance created by variations in yarn thickness. They can be a good option when the design calls for a more natural, irregular surface.

Duck and Canvas Fabric

Duck and canvas fabrics are often considered for products that need a firmer or more substantial feel. The exact characteristics depend on the weave, weight and fibre composition.

5. Check the Fibre Composition

The words used to describe a fabric do not always tell you exactly what it contains.

Some fabrics are made from cotton, while others may contain polyester or a blend of different fibres. A fabric's composition affects its feel, care requirements and performance.

For example, a polyester-cotton blend is different from a fabric made entirely from cotton. Neither description alone guarantees that the material will suit a particular product.

Always confirm the fibre composition of the exact specification you are purchasing. If the product needs a specific composition, ask for that detail to be included in the approved order specification.

6. Think About Finishing and Shrinkage

The fabric you receive after finishing may not behave exactly like an unfinished material. Dyeing, printing, washing and other treatments can affect its colour, surface, dimensions and feel.

Shrinkage is particularly important when making products with precise measurements. A fabric that changes size during washing may affect the finished dimensions of a garment, curtain, tablecloth or bedding item.

If the final product will be washed regularly, discuss the expected care process and shrinkage allowance before production. Where possible, test a sample using the intended finishing and washing method.

For printed products, it is also worth confirming the desired colour, print placement and colourfastness requirements.

7. How to Choose Fabric for Different Products

There is no single fabric specification that works for every product. The following examples can help you decide what to discuss with your supplier.

Apparel: Consider softness, drape, breathability, weight and how the fabric feels against the skin. The best construction depends on the design.

Bags and accessories: Look at body, sewing behaviour, expected load and the structure required by the finished product. A lining may also affect the choice.

Curtains: Consider the way the fabric falls, its width, light requirements and how it will be maintained.

Table linen: Check the required dimensions, drape, texture, washability and finishing. Fabric width can influence how efficiently larger pieces can be cut.

Bedding: Consider softness, skin comfort, care requirements, construction and dimensional stability after washing.

These are starting points rather than guarantees. Always match the actual fabric specification to the product's performance requirements.

8. Questions to Ask Before Placing a Bulk Order

Before confirming a fabric order, make sure you and the supplier are working from the same specifications.

Here are the details worth checking:

What is the exact fibre composition?

What are the fabric construction and GSM?

What is the usable width?

Is the quoted weight for the finished fabric?

What finishing, dyeing or printing is required?

Is a sample available for approval?

What shrinkage or colourfastness information can be provided?

What quantity is available, and what is the production lead time?

How will the fabric be packed and shipped?

Not every project requires the same level of testing, but asking these questions early can reduce confusion later.

9. Why Sampling Is Worth the Time

A specification sheet gives you important information, but it cannot show you everything about a fabric.

A sample lets you assess the actual colour, texture, drape, thickness and handling. You can also test whether it works with your cutting, sewing, printing or washing process.

For repeat orders, keep a record of the approved sample and specification. This gives your team a useful reference when discussing future production.

If you are developing a new product, it is usually better to identify a mismatch during sampling than after a large quantity has been produced.

10. Choosing a Fabric Supplier in India

When sourcing fabric, look for clear communication and accurate specifications rather than relying only on a product name or photograph.

A useful supplier conversation should cover the intended product, construction, GSM, width, fibre composition, finishing and required quantity. If your requirements are unusual, explain them at the beginning instead of waiting until the order is ready.

At BOHOBLOCKPRINTED, we encourage buyers to share their actual product requirements so that the available fabric specifications can be reviewed against their needs.

Before confirming a bulk order, make sure the agreed details are documented. This is particularly helpful when the order requires a specific width, blend ratio, finish or repeat production schedule.

Frequently Asked Questions

What is the most important factor when choosing cotton fabric?

There is no single factor for every project. Start with the intended product, then compare construction, GSM, width, fibre composition and finishing.

Does higher GSM always mean better quality?

No. GSM measures fabric weight, not overall quality. Construction, yarn quality, fibre content and finishing also matter.

Why should I check fabric width before ordering?

Width affects cutting efficiency, material consumption and whether large product pieces can be made with fewer joins.

Is every fabric described as cotton made from 100% cotton?

Not necessarily. Always check the fibre composition of the exact material, especially when a product requires a specific blend.

Should I request a sample before bulk purchasing?

A sample is useful when the fabric's feel, appearance, dimensions or performance matter to the finished product. It allows you to assess the material before committing to a larger quantity.
