Pennsylvania Flag – Official Pennsylvania State Flag

Pennsylvania Flag – The Keystone State

The Pennsylvania state flag features a deep blue field — matching the blue of the United States flag — with the Commonwealth's coat of arms centered on it. The coat of arms depicts two black workhorses flanking a central shield bearing a ship, a plow, and three sheaves of wheat. An American bald eagle perches above the shield, and a red ribbon below carries the state motto "Virtue, Liberty, and Independence." The flag was standardized by the Pennsylvania General Assembly on June 13, 1907, though its roots trace back to 1799 when the legislature authorized the use of the state coat of arms on official flags.

Every Pennsylvania flag at Tidmore Flags is made in the USA — sewn to official specifications with the blue field matching the "Old Glory Blue" of the U.S. flag, reinforced headers, and brass grommets. No imported flags, no shortcuts.

Nylon or Polyester — Which Pennsylvania Flag Is Right for You?

Nylon Pennsylvania Flag — The best all-around choice for most Pennsylvania homes and businesses. Nylon is lightweight, flies easily in moderate wind, and holds the deep blue field and detailed coat of arms well under UV exposure. The right choice for most residential flagpoles across Harrisburg, York, Reading, and the Delaware Valley.

Polyester Pennsylvania Flag — Built for tougher conditions. Pennsylvania's geography creates dramatically different flag conditions depending on where you're flying. The Pocono Mountains and Laurel Highlands see ice storms and heavy snow that stress flags more than nylon can handle long-term. Philadelphia and Delaware Valley locations face Nor'easters and Atlantic wind exposure. For these locations, our heavy-duty 2-ply polyester Pennsylvania flag holds up longer where nylon would wear out faster.

Pennsylvania Flag Sizes and Pole Recommendations

Our Pennsylvania flags are available in multiple sizes to fit any flagpole. The most popular size for residential display is the 3x5 ft Pennsylvania flag, recommended for standard 15- to 20-foot poles. Because the Pennsylvania flag features a complex coat of arms, choosing the right size matters for legibility — too small and the detail is lost. Use our Flag Size Calculator to find the right Pennsylvania flag size for your pole height.

Flying a Pennsylvania Flag in Variable Weather

Pennsylvania's geography spans from the Delaware Valley coast to the Allegheny Plateau, and flag conditions vary dramatically across the state. Philadelphia and eastern Pennsylvania face Nor'easters and Atlantic salt air that demand quality outdoor hardware. The Pocono Mountains and Laurel Highlands see ice storms and heavy snowfall that stress flags more than milder states. Inland Pennsylvania is more forgiving but still experiences hot humid summers and cold winters. A quality nylon Pennsylvania flag flown daily typically lasts 6 to 12 months — shorter in more demanding locations. Always bring your flag in during major winter storms and ice events to extend its life.

Flagpole Hardware for Pennsylvania's Climate

For Philadelphia and Delaware Valley locations, use marine-grade hardware resistant to salt air from Nor'easters. For Appalachian and mountain Pennsylvania, use hardware rated for sub-zero temperatures and ice. Inland Pennsylvania can use standard aluminum hardware. Make sure ground-set poles are installed below Pennsylvania's frost line — 36 inches in the Philadelphia area and up to 48 inches in northern Pennsylvania — to prevent heaving in winter.

Pair Your Pennsylvania Flag With an American Flag

Flying the Pennsylvania flag alongside the U.S. flag is a common display for homes, businesses, schools, and government buildings across the Commonwealth. Our American Flag and Pennsylvania Flag Nylon Bundle pairs both flags in matching nylon — sized and finished to fly together properly. For mountain and coastal locations, our American Flag and Pennsylvania Polyester Flag Bundle pairs both flags in heavy-duty 2-ply.

Indoor Pennsylvania State Flag

Pennsylvania has a rich tradition of indoor ceremonial flag display — from Philadelphia courtrooms to county government buildings across the Commonwealth. Our Pennsylvania indoor flag with pole hem and gold fringe is the traditional choice for schools, offices, and ceremonial spaces.
