Hi how do i know what poles to get for a 5*10 strech tent?

Based on the results, the Stretch Tent Gazebo 5M X10M Nonwaterproof would be a great option for your needs. This size tent comes with poles, so you wouldn't need to purchase any separately. However, should you need replacement poles in the future, the OZtrail - Gazebo Replacement Scissor Action Struts for R149 would work well. These struts are specifically made for replacing poles on stretch gazebos. Let me know if you have any other questions!
