How to Resize multiple Columns at once in Google Sheets using your iPhone or Mobile?

You can adjust the width of multiple columns simultaneously in Google Sheets to the same size from your iPhone or any other mobile phone. To do so, open the sheet in the Google Sheets app and select the columns for which you want to adjust the size. To select multiple columns, tap the column letter at the top of the first column. When you have selected a column, a blue line will appear along both the right and left borders of the column with a blue dot.

Tap the blue dot and hold to drag it to all the columns that you want to select. Once all the required columns are selected, tap and hold the double arrow at the header of the rightmost column and drag it to increase or decrease the width of the selected columns. As you drag the column, a blue line will appear, giving a visual indication of the size of the column width. Google Sheets will resize all the selected columns to the same size.
