Vintage Moroccan rugs are typically more narrow than their modern counterparts. The homes they were woven for were long and narrow, which is why common sizes are around 180cm-215cm (6-7ft) wide and 275cm-400cm (9-13ft) long.
Sometimes, rug size "rules" can be bent to come up with a solution for your space. Other times, a bespoke rug may be the best solution. Not sure? Feel free to email me at firstname.lastname@example.org with photos of your space and overall desired look.
