Delaware State Flag Size Guide: What Size Delaware Flag Should You Fly?

Display Standards for the First State
Technical Standards for Maritime Winds, Historic Corridors, and Bay-Front Durability
The Delaware state flag, featuring its distinctive Colonial Blue field and Buff diamond, carries the heavy historical weight of the nation's "First State." However, displaying the coat of arms and the "December 7, 1787" scroll requires more than just pride—it requires a technical understanding of Delaware's maritime microclimates. Whether you are flying the diamond in the historic streets of Old New Castle, the open farmlands of Kent County, or the salt-heavy breezes of Rehoboth Beach, your flag must be engineered for its specific environment.
Delaware’s geography creates unique "wind-funnel" effects along the Delaware River and the Atlantic coastline, where high-humidity air meets varying wind velocities. This leads to increased "textile fatigue" compared to inland states. This authoritative guide provides the precise sizing and material specifications required to maintain a dignified Delaware display against the rigors of the Mid-Atlantic coast.
The Physics of Display: Flag-to-Pole Scaling
For Delaware's diverse architectural landscape—ranging from colonial brick to modern coastal builds—proper scaling is essential for visibility. The industry-standard 1:4 Ratio ensures that the intricate details of the state seal are legible. In the Sussex County beach regions, where flags are often viewed from long distances across dunes or water, "upsizing" for increased visibility is a common technical recommendation.
| Flagpole Height | Recommended DE Flag Size | Regional Context |
|---|---|---|
| 5' - 6' (Wall-Mount) | 3' x 5' | Historic Districts (New Castle, Lewes) |
| 20' (Residential) | 3' x 5' or 4' x 6' | In-Ground Lawns (Wilmington, Newark) |
| 25' (Commercial) | 5' x 8' | Corporate Plazas & State Offices |
| 30' - 40' (Flagship) | 6' x 10' or 8' x 12' | Municipal Hubs & Port Facilities |
Material Intelligence: Defeating the Coast
The Coastal Shield: 2-Ply Spun Polyester
If your flag is located within the Delaware Bay fetch or along the Atlantic coastline (Bethany Beach, Fenwick Island), we mandate 2-Ply Spun Polyester. This open-weave material allows high-velocity coastal winds to pass through the textile, reducing the "crack" at the fly end. It is the only material robust enough to survive the combination of high-UV exposure and salt-spray abrasive action common in Delaware’s maritime zones.
The Inland Standard: 200-Denier Nylon
For residential displays in protected areas of Wilmington, Hockessin, or Dover, 200-Denier Nylon is the authoritative choice. This lightweight fabric flies in as little as a 2-mph breeze, ensuring the Colonial Blue and Buff colors stay in motion. Our nylon is treated with specialized UV-blockers to preserve the precise historical shades of the Delaware diamond against the humid Mid-Atlantic summer sun.
If you’re deciding between fabrics, understanding how long Delaware flags last outdoors can help you choose the right material for your environment.
The First State Display Protocol
When flying the U.S. Flag and the Delaware Flag on a single pole, the U.S. Flag must be at least one size larger or equal to the state flag. On a standard 20-foot residential pole, the most balanced and respectful combination is a 3'x5' U.S. Flag positioned above a 3'x5' Delaware Flag. During Nor’easter warnings or severe storm surges, all flags should be lowered to prevent halyard failure and textile destruction.
Frequently Asked Questions (FAQ)
Q: Why does the Colonial Blue on my Delaware flag look faded?
A: Prolonged exposure to Mid-Atlantic UV and salt air can cause pigment breakdown. We recommend rotating your flags every 4-6 months and opting for UV-treated nylon to maintain the historical Buff and Blue shades.
Q: Can I wash a Delaware flag that has been exposed to salt spray?
A: Yes. In coastal Delaware, we recommend a light freshwater rinse every 60 days. This prevents salt crystal buildup, which acts as an abrasive and weakens the textile fibers over time.
