The flag of Houston is the official flag of the city of Houston. It consists of a large white five-pointed star on a blue background with the city's seal set within the star. The flag was adopted in 1915.
The city seal was adopted in 1840. It depicts a 4-4-0 locomotive, ironically before any railroad reached Houston.
Most mass-produced flags are commonly 150x90cm / 5x3' or 90x60cm / 3x2', which will often vary from the official size ratio. We now offer a custom-manufactured official size option for our many of our flags.
