thanks for replying. The software is not great but tbh the person I dealt with kept on about some of the free handles and that it's standard for the same size handle to be used all over the one kitchen and that only a handle small enough for the two small doors decided the size for all doors/drawers. The drawers are only 80cm wide but still...

It's my first, probably last, time buying a kitchen so it's taken ages and lots of to-ing and fro-ing.

I suppose I didn't feel listened to and i'm spending £20k!

Oh dear - that’s one way - but not the only way !
If you choose a handle that comes in small, medium and large then you can mix them - ask for print outs of elevations to scale - then try the different handle sizes drawn onto tracing paper over the top - or draw them in pencil etc ... you will be living with this for a long time - it’s worth a bit of time now to get it right !

Nb. The handles don’t have to be the same even - as long as they are the same finish - I have knobs, cup handles and two sizes of grab handles on my own kitchen - and it looks great (IMO) .
