Grommet spacing refers to how far apart the metal eyelet holes are placed along a banner’s edges, typically installed every 2 to 3 feet around the perimeter. Proper spacing ensures a banner hangs evenly and distributes wind and tension stress across multiple mounting points rather than concentrating it in just the corners.
Why Grommet Spacing Matters
If grommets are placed too far apart, the unsupported sections of banner between them can sag, billow in the wind, or place excessive stress on the grommets that do exist — increasing the risk of tearing. Properly spaced grommets keep the banner taut and evenly supported along its full length.
Standard Grommet Spacing Guidelines
- Every 2–3 feet along the top and bottom edges is the most common standard, suitable for most everyday outdoor and indoor banner applications
- Corners always get a grommet, roughly 1–2 inches in from each edge, as a baseline regardless of overall banner size
- Every 1–2 feet for high-wind areas or larger banners, where more frequent support points reduce stress on any single grommet
Where Grommets Are Typically Placed
- All four corners, as a baseline for any banner
- Along the top edge, primarily if the banner is hung from above (most common setup)
- Along the bottom edge, if the banner needs to be secured at the bottom as well, particularly in windy conditions
- Along the sides, if the banner will be mounted on a fence or between two vertical points rather than hung freely
Customizing Grommet Placement
Most online banner printers allow you to specify grommet placement based on your specific mounting situation — top only, all four sides, or a custom configuration. It’s worth thinking through exactly how and where the banner will be displayed before finalizing this, since the right placement depends entirely on your mounting method (wall-mounted, fence-tied, hung from a frame, etc.).
What Happens With Insufficient Grommets
A banner with too few grommets, or grommets spaced too far apart, is more prone to tearing at the existing grommet points, especially in windy conditions — the wind load that would normally be spread across many points instead concentrates on just a few, exceeding what the material and hardware can handle.
The Bottom Line
Standard grommet spacing of 2–3 feet works well for the majority of banner applications, but the right spacing ultimately depends on banner size, expected wind exposure, and mounting method. When in doubt, specifying grommets on all sides with somewhat tighter spacing is a low-cost way to add durability, particularly for banners that will be displayed outdoors for extended periods.
