Actually I have two of the mats! I bought-one which was 13” wide by 12 feet long and then cut off 3feet , as a mat to stand on. I’ll attach a photo on how I use it. I figure practicing on 5 to 6 footers was most important. I bought the slower version, because our greens in my area are not what I consider really fast. I also use a broom to sweep against the “grain” to slow the roll. The other one I have takes too much space (4X12). It is a good product and I would recommend it. If you ask for a sample from the company they will send you a sample. I like mine, but there are other options. As you can see in the pics, I use parallel bars to practice, now I only use the one on the inside ( helps me not loop the putter), as well as a Eyeline mirror for eye alignment and putter squareness., as well as a cup reducer. It has really helped my putting.
