The magic number seven
In 1956 psychologist George Miller described the "magical number seven, plus or minus two" — the rough limit of items we can hold in short-term memory. Digit span tests like this one are the classic way to measure it, and most adults recall 7–8 digits.
How to remember longer numbers
Split the number into chunks, the way phone numbers are written: 4821 9375 is far easier than 48219375. Say the chunks in your head with a rhythm. With practice, chunking can push digit span well past ten.
