30' × 50' Made in USA American Flag | Eder Landmark Series

"Big Sister"

Big Sister commands attention long before you reach the property. At 30 feet by 50 feet and 44 pounds, this Made in USA American flag from Eder is built for large-scale commercial and civic installations where presence matters and quality is non-negotiable.

Designed for flagpoles in the 125–150 foot range, this size delivers serious visual impact without stepping into the extreme scale of the largest monumental flags. Handcrafted in Wisconsin by the employee-owners of Eder Flag—America’s largest and most trusted flag manufacturer—Big Sister is engineered for long-term performance in high-visibility environments.

Ideal for large-scale installations

• 30' × 50' commercial American flag applications

• Regional government buildings and civic centers
• University campuses and institutional facilities
• Large retail developments and community landmarks
• Replacement flags for 125–150 foot flagpoles

Where Big Sister makes her mark

This size strikes the balance between monumental presence and practical installation. It’s large enough to define a skyline presence while remaining manageable for professional commercial installations.

• Corporate campuses and headquarters
• Regional civic buildings and memorial sites
• Community colleges and university grounds
• Major event venues and fairgrounds
• Large commercial and mixed-use developments

Built for the long haul

At 44 pounds and 1,500 square feet, this heavy-duty American flag is engineered to handle demanding wind conditions and continuous outdoor display:

• Choose your material: Premium 200-denier nylon flies beautifully in light breezes and resists fading, or battle-tested polyester for extreme durability in high-wind commercial environments
• Reinforced stress points: Extra stitching at corners and fly end where wind stress concentrates—the difference between a flag that lasts and one that doesn't
• Fade-resistant treatment: Aniline-dyed and UV-treated to maintain vibrant colors under constant sun exposure
• Authentic construction: Appliquéd stars and individually sewn stripes, crafted the traditional way for strength and longevity

A familiar landmark presence

This is the size you see flying at major corporate campuses, regional civic centers, and prominent community gathering places. Large enough to command attention from a distance, Big Sister creates a lasting visual anchor for the property it represents.

The pole that carries Big Sister
