Our sofa is 80L 40 W 38H. What size do I need?
According to your describing for the loveseat , I do not think our loveseat cover will fit it.The loveseat cover standard M size is the closest one.
They have wiggle room so based on my experience your only choice to try is the standard small size based on the measurements you supplied. Remember i am a consumer not the seller. Your height is the only "iffy" question and Im sure there will be plenty of extra to fit that as close as possible. Good luck!
The Standard-L loveseat cover size you have bought is : 34"D x 90"W x 32"H(L) . And The maximum size of a suitable loveseat size for this size loveseat cover is: 32.5"D x 88"W x 33"HIf the loveseat cover is not suitable for you,you could apply for return through amazon and amazon will give you refund.
