We have created a simple Magnification Chart to give an approximate guide to magnification. Our starting point is normal 10-point newspaper text – as found in The Times for example. We suggest you print out the sheet and cover all but the top box of text, then scroll down until you find a magnification strength (circled) that is most comfortable. Alternatively if you cannot read 10-point text you may wish to start with another passage and work out roughly what magnification is best for you by gauging the relative increase from your starting point up to the next most suitable magnification.
