I am using ArcGIS Pro, polygon to raster tool. I am converting a large set of polygons (over 100,000) into a raster, using a cell size of 0.0016 (the default is 0.0098). When the operation is complete, it creates cells that are very stretched out horizontally. The cells seem to be the correct vertical distance, but are way too wide. I tried the operation with the same inputs but on a small selection of polygons, and it worked fine.
