What Are Rectangle Flags?

Rectangle flags, also called L flags, are outstanding marketing designs on a pole, suitable for indoor and outdoor use. They catch the eye and keep your message visible from afar. They give businesses a portable medium to promote any message.

Custom rectangle flags solve the poor visibility problem with vibrant visuals and a vertical design. They stand tall in windy conditions and don’t tear up thanks to their premium polyester material.

Retail stores use them to announce sales and promotions. Corporate events, grand openings, trade shows, and sports venues use them to display clear messages. Rectangle flags offer businesses the means to maintain a strong presence in high-traffic locations.

Material and Printing of Rectangle Flags

Rectangle flags consist of a polyester fabric flag and an aluminum pole set. Polyester fabric keeps colors sharp and holds up in windy conditions and moderate weather. The base keeps the flag stable and secure.


We print custom rectangle flags with dye sublimation technology. This printing method allows the ink to seep into the material at a molecular level, resulting in fade-resistant colors that last for many years. Pick from three options to get the visibility your business needs:


  • Single-Sided: Print appears on one side only. The print may be slightly visible from the reverse under strong light;
  • Reverse-Sided: This option uses mirror-printed graphics on one side that bleed through to the other. It’s lighter, has better wind response, and costs less as it uses only one layer of material.
  • Double-Sided: Carries full imagery on both sides to double the visibility. Use a flag with this option in environments where viewers approach from multiple directions.

Setup Options

You can assemble and set up a rectangle flag with a support structure. We offer four base types for installing your flag in different settings.


  • Ground stake drives into the ground and secures a stable outdoor setup. It is ideal for large flags that need a firm grip;
  • Square base features a heavy metal with a flag pole insert that supports medium to large rectangle flag banners. It works well on flat surfaces and provides good stability;
  • Cross base is a four-legged option perfect for small rectangle flag banners. It deploys fast and is perfect for indoor use;
  • Cross base + water bag adds a water bag to the cross base for extra weight. It makes your rectangle flag stay upright even in breezy conditions.

Rectangle Flag Installation and Care

You can set custom rectangle banners in minutes. You don’t need any tools or professional help. Everything you need to do is attach the pole set, slide the fabric over it, and secure the base. 
Select the base that fits the environment where you plan to install the flag. To compare all four base types, check the setup options section.

Wipe the flag with a damp cloth to clean it and keep it ready for reuse. Avoid cleaning it in a washing machine. If you absolutely have to, then do it on a gentle cycle with cold water. 
Store your product in a dry place when not in use to protect the material and extend its life.

FAQs

What material do you use to print custom rectangle flags?

We use tear-resistant polyester fabric for the product. It holds up well in windy weather and doesn’t fade under prolonged sun exposure.

What sizes do rectangle flag banners come in?

The three sizes we offer for the product are 31” x 90.5”, 31” x 114”, and 31” x 151.5”.

The smallest (31” x 90.5”) is suitable for indoor displays or events with limited space.

The medium-sized variant (31" x 114") works at both interior and exterior venues. You can find rectangle flags of this size at trade shows or promotional events.

The largest size (31” x 151.5”) provides maximum visibility in open outdoor areas during festivals, at sports venues, or in parking lots.

Will the flag come in matte or gloss finish?

Rectangle flags come with a matte finish by default. As these displays are generally set up outdoors, their finish needs to reduce glare.

Can I print different designs on the front and back of the flag?

Yes. Double-sided rectangle flags support different designs on each side.

Can I order a rectangle banner without the pole set?

Yes, select the option of No Pole Set while placing an order to only receive the flag.

What is the weight of the flag bases?

The weights of flag bases are as follows:


  • Ground Stake: 0.2833 lbs;
  • Square Base: 1.8333 lbs;
  • Cross Base: 0.55 lbs;
  • Cross Base with Water Bag: 0.55 lbs.

Will the wind blow my flag over?

We use wind-resistant polyester fabric to make our rectangle flags to reduce the risk of your flag falling over. Use a cross base with a water bag to weigh down your flag and keep it upright in windy conditions.

Will the sun damage my design?

No, it won’t. We use dye sublimation printing that binds the ink to the material at a subsurface level during the printing process. This ensures that the colors remain fade-resistant over time.

How to create a unique rectangle banner design?

Start with a clear message and a single focal point. Use bold, readable fonts and high-contrast colors to make your design visible from a distance.

Keep the layout clean and avoid overcrowding the flag with too much text or imagery.

Upload your design to our free sign design tool, choose your product size, print option, and base, then place your order.

How long will the rectangle banner last?

Our rectangle flags will serve you for at least two years.

How should I take care of my rectangle flag?

Caring for this product takes minimal effort. You need to wipe the flag with a clean, damp cloth to remove dust and dirt. Store it in a cool, dry place when not in use to keep it in good condition.

Can I wash my custom rectangle flag?

It will be better if you avoid washing the flag. If you want to do it anyway, then wash it on a soft cycle with low-temperature water.

Five stars for the quality, speed and design of my rectangle flags. I used them for the fall product line at my store. They arrived just in time even though I got them last minute which I’m so happy about. Thanks again.

I got a double-sided rectangle flag banner from Square Signs for a great price. The graphics were vibrant and I can't get enough of the compliments we get on the design. Thumbs up to your design tool.
