The main hall rug is the centerpiece of your entrance, so you want it to make an impact. There are several factors to consider when shopping for a main hall Persian rug. First, consider the size of your hall. A good rule of thumb is to choose a carpet about two-thirds the size of the space. Next, consider the style of the rug. Persian rugs are known for their intricate designs and rich colors, so that they can add a lot of visual interest to a central hall. However, you'll want to choose a rug that complements the overall décor of your home. If you have a more traditional style, a carpet with a classic pattern like floral or medallion might work well. If your style is more modern, then go with something simpler, like geometric designs.
