You can get Bitmap dimensions only after downloading It - you must use synchronous method call like this:

final Bitmap image = Picasso.with(this).load("http://").get();
int width = image.getWidth();
int height = image.getHeight();

After this you can call again load with same url (It will be fetched from cache):

 Picasso.with(this).load("http://").into(imageView)

Edit: Maybe better way:

 Picasso.with(this).load("http://").into(new Target() {
            @Override
            public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                int width = bitmap.getWidth();
                int height = bitmap.getHeight();
                imgView.setImageBitmap(bitmap);
            }

            @Override
            public void onBitmapFailed(Drawable errorDrawable) {

            }

            @Override
            public void onPrepareLoad(Drawable placeHolderDrawable) {

            }
        });
