The closest I have seen to OE style headliner material for E36/Z3 coupe models
 
Sold by the yard
The width of the material is 58"
Buying one yard gives you 36" x 58"
Buying three yards gives you 108" x 58"
 
Note: The VW Fabrics are a little wider than 58" but the last few inches may need to be folded to fit into the box and may develop some wrinkling as a result, but will have 58" of usable area
 
For those who use metric
The width of the material is 1.47 meters
Buying 1 yard gives you .91 meters x 1.47 meters
Buying 3 yards gives you 2.8meters x 1.47 meters
