As you can see, the width of allowed hand baggage varies depending on the airline up to 10 cm. It is also important to note that with low cost airlines the allowed weight for both checked baggage and for hand luggage is different, so you should consult it on their websites, since they are extremely strict with the weight and often charge very high billing rates for each kilo of exceeded weight.
