No, those squares are not too small if you have the will and desire. I sewed this quilt for my husband using the grid method. My squares finished at 1/2". I trimmed down my seam allowance to 1/8" to help with bulk. Here's the pic of mine.
It came out far better than I expected and there is no way I personally could have done it without the grid.
