Choosing the correct gobo size is one of the most important steps when buying a rotating gobo projector. Many customers ask a simple question: Is a 37mm gobo large enough, and how does gobo size affect projection quality?The answer depends on the projector design, installation distance, image complexity, and whether the projection will be static or rotating.
What Is a Gobo in a Rotating Gobo Projector?A gobo is a specially manufactured image template installed inside a projector. Light passes through the gobo and creates a projected logo, message, pattern, or graphic on a wall, floor, building, or other surface.In a rotating gobo projector, the gobo slowly rotates to create movement, making the projected image more eye-catching than a fixed logo. Rotating projections are widely used for retail stores, hotels, events, exhibitions, shopping centers, and outdoor advertising.
Why Is Gobo Size Important?Many buyers focus only on projector power, but gobo size also affects image quality.A larger gobo can contain more design details, making it suitable for complex logos and graphics.A smaller gobo often works well for simple text, symbols, and logos while keeping the projector compact and cost-effective.The optical system of the projector is designed around a specific gobo diameter. Using the correct size ensures proper focus, brightness, and image sharpness.
Is a 37mm Gobo a Standard Size?Yes. A 37mm gobo is one of the most common sizes used in commercial and advertising logo projectors.This size provides an excellent balance between image detail and projector efficiency. It is widely used in:Shop logo projection, Retail advertising,Hotel branding,Exhibition displays,Indoor and outdoor promotional lighting,Event entrance projection.For many rotating logo projector applications, a 37mm gobo offers enough space for detailed logos while maintaining high brightness.
How Large Can a 37mm Gobo Projection Become?The projected image size depends on the lens and projection distance rather than the gobo diameter alone.Taking the widely used 37mm gobo paired with a standard 1:0.33 lens ratio and 65W projector as an example,the actual projection dimensions are as follows: the projected logo reaches about 1 meter at a 3-meter projection distance, approximately 1.6 meters at 5 meters, and around 2.6 meters at 8 meters or longer distances.This flexibility makes the 37mm gobo suitable for both small indoor projects and larger commercial installations.
Can a 37mm Gobo Support Rotation?Absolutely.Our Noparde modern rotating gobo projectors use precision motors that rotate the gobo smoothly without affecting image quality.Slow rotation is commonly used for luxury branding, restaurants, and hotel entrances.Faster rotation can attract attention for events, promotions, and temporary advertising campaigns.The rotation speed can often be adjusted depending on the projector model.
What Type of Artwork Works Best?Simple logos usually produce the brightest and sharpest results.For best performance, manufacturers typically recommend:AI files,EPS files,SVG files,PDF vector artwork.Vector artwork allows precise manufacturing of custom gobos and helps preserve fine details during projection.
A retail chain in Germany recently upgraded several storefronts with rotating gobo projectors using 37mm custom logo gobos.The projected logos were visible from long distances during evening hours, helping customers identify store locations more easily. Compared with traditional printed signs, the rotating projections attracted more attention while requiring very little maintenance.
