Project raster - cell distortion

Greta

Hi

I project a raster from a projected coordinate system to WGS84. I tried the three methods provided by the tool "Project Raster" and kept the cell size of the original raster, but it always slightly distorted the cell size.
Can we project the raster without distorting the cell size?

Thanks

Greta

current default to give you some guidance is

When projecting from GCS to PCS, or PCS to GCS, the output cell size is calculated based on the average of the ratios of the four sides and the two diagonals of the projected extent to the original extent. This is the default.
