The basic reason we incorporate measurements in our daily lives is to ensure precision and make our decisions accordingly. However, when we specifically speak of banners material weight, we measure them either in GSM (grams per square meter) or in Ounces. While keeping the precise measurements in mind, it plays a crucial role in its durability, appearance and how well does it suit various applications.
Let’s dive into the essential concepts behind banner material weight, comparing GSM and ounces, and explore how to choose the correct weight for your needs.
The weight of a banner material essentially refers to its thickness and density, impacting how it feels, hangs and performs under various conditions. Material weight can be measured in GSM (grams per square meter) or ounces (oz). Understanding banner weights is vital when deciding on the right thickness and durability for a banner, as these factors directly impact its suitability for different environments, weather conditions, and lengths of use.
GSM (Grams per Square Meter): GSM is a metric measurement that indicates the weight of a material over a one-square-meter area. The higher the GSM number, the denser and heavier the fabric, which usually results in better durability and resilience. GSM is commonly used in fabric banners and materials outside the U.S. due to its standardized global applicability.
Ounces (oz): In the U.S., banner weight is often measured in ounces per square yard. Similar to GSM, a higher ounce weight generally means a thicker, more durable banner. Ounces are commonly used to measure vinyl and heavy-duty materials.
While GSM and ounces measure similar aspects of banner thickness and durability, they are different units. Understanding these differences through a banner thickness guide is essential to help you compare materials effectively. A reliable guide provides insights into how GSM and ounces correlate with thickness, enabling you to choose the right balance of weight and flexibility for your banner needs.
How to choose banner weight that’s right for your custom banners depends on multiple factors, including location, intended duration of use, environmental exposure, and design needs. Here are a few guidelines to help you make an informed choice.
Consider the Location of the Banner: Outdoor banners generally require a heavier, more durable material than indoor banners to withstand weather conditions like rain, wind, and sun exposure. For outdoor use, vinyl banners are popular due to their durability and waterproof features. A vinyl banner weighing around 13-18 oz is usually suitable for outdoor usage.
Indoor banners, on the other hand, can be made from lighter-weight materials like fabric banners with lower GSM ratings. Typically, fabric banners in the range of 115-250 GSM provide sufficient durability for indoor environments without adding unnecessary weight or stiffness.
Determine the Intended Duration of Use: For banners that need to last for a long time—months or even years—opt for a heavier, high-GSM or high-ounce weight material that provides long-lasting durability. Heavier weights are generally more resistant to wear and tear, especially when exposed to environmental stressors. Banners used for short-term events, such as trade shows, exhibitions, or indoor promotions, can often be lighter in weight.
Evaluate Environmental Exposure: Banners placed in harsh weather environments, such as areas prone to high wind or rain, benefit from a higher GSM or ounce weight. Additionally, double-sided vinyl banners, typically around 18 oz, are ideal for outdoor use due to their resilience and ability to display information on both sides effectively.
For indoor settings, environmental exposure is typically limited to factors like artificial lighting, making it possible to opt for lighter fabric banners or lower-GSM materials without compromising on the display quality.
Understand Banner Thickness Guide: Material weight impacts banner thickness, influencing how the banner feels and looks. A higher GSM or ounce weight results in a thicker, stiffer banner. The thickness not only affects the durability but also determines how the banner hangs. A banner that is too thick may appear stiff and less fluid, which can impact its visual appeal in some indoor settings.
Both vinyl and fabric are popular choices for banners, each offering distinct benefits.
Vinyl Banners: Vinyl is the go-to option for outdoor banners, offering durability, vibrant print quality, and weather resistance. Vinyl banners are often available in weights ranging from 10 to 18 oz, with heavier options designed for outdoor and double-sided use. A 13 oz vinyl banner, for example, is commonly used for outdoor applications as it offers a good balance between durability and flexibility. Custom banners made from 15 oz vinyl or higher are generally used in high-wind areas or long-term displays.
Fabric Banners: Fabric banners, typically made from polyester, are lightweight, easy to transport, and offer a soft, elegant look. Fabric banners in the range of 115-250 GSM are popular for indoor use, trade shows, and exhibitions where the material’s lightweight nature makes setup and storage convenient. The lower GSM also allows for crisper, more vibrant prints with a softer, more professional look.
If you need to compare GSM and ounces, here’s a quick conversion to give you a rough idea of how the two measurements correlate.
| GSM | Approximate Ounces/Yard² | Common Usage |
| 115 GSM | 3.4 oz | Lightweight indoor fabric |
| 180 GSM | 5.3 oz | Indoor/outdoor fabric banners |
| 230 GSM | 6.8 oz | Durable indoor fabric banners |
| 340 GSM | 10 oz | Standard vinyl for indoor use |
| 440 GSM | 13 oz | Outdoor vinyl banners |
| 610 GSM | 18 oz | Heavy-duty, outdoor, double-sided vinyl |
This table can guide your choices based on the material type and intended usage. A heavier weight is generally suitable for outdoor settings, while lighter weights are best kept indoors or for short-term displays.
Each unit has its own advantages and disadvantages, especially when it comes to material selection for banners.

Selecting the right weight for custom banners is vital to ensuring that the banner meets both aesthetic and functional requirements. Here’s a quick breakdown based on common needs:
Event Banners (Short-Term Indoor Use): 115-180 GSM or 3-6 oz for lighter, fabric banners
Indoor Retail Displays (Long-Term Use): 200-300 GSM or 6-8 oz for durability without excess weight
Outdoor Promotions (Moderate Weather): 13 oz vinyl or approximately 440 GSM for durability and visibility
High-Wind Outdoor Displays: 15-18 oz vinyl or above 610 GSM for maximum resilience
Understanding banner weights and the differences between GSM and ounces enables you to select a banner material that best suits your display’s environment, purpose, and longevity. Whether you need a robust vinyl banner for outdoor advertising or an elegant, lightweight fabric banner for a trade show, knowing how to evaluate material weight ensures you get the quality and durability you need.
By using this knowledge, you can confidently order custom banners that meet specific requirements, ensuring that your investment pays off in both performance and appearance.
