Quick kicthen sink measurement and size question

[earlycomputers]

Just wondered if I could have some quick advice re kitchen sink measurement as I want to be sure I buy the right sized replacement sink. I see that sink widths and lengths come in standard sizes, but when I measured my sink it falls between two of these standard sizes - i.e. 98.5cm length by 50.3cm. So would I get a sink measuring eg 100cm in length or 98cm in length for instance? Do I buy bigger than I think or smaller? Many thanks

Bigger, the hole can always be increased a little but if you buy small there will be a gap at the end. Make sure if you buy wider though, that your worktop has enough room to cut the hole and leave enough for the integrity.

Can`t you see the size of the current one from underneath the worktop.
