what this returns is a
the value of the ref is the image + dimensions + file type as one string. break the string at the
then find the index where the image dimensions are returned. parse the image dimensions to find the aspect ration
w / h

strike that. there is actually undocumented api to get the image dimensions from the ref in the validation:
const {width, height} = getImageDimensions(image.asset._ref)

comes from
import { getExtension, getImageDimensions } from '@sanity/asset-utils'

Rule.required().custom(image =>{
const arr = image.asset._ref.split("-");
let dimension=arr[2];
const res=dimension.split('x');
let width=res[0]
let height=res[1];

const aspectRatio = width / height;
if (aspectRatio===1/1) {
} else {
return "The aspect ratio is not 1:1";
I did like this it worked thank you for the guidance .
