This will depends on the look you’re after. If you like a soft cushion look, you should choose the same size insert as the cover.

For a plump and filled out look, you should get an insert that is one size bigger. Here are our recommendations:

Cushion Cover Size     Insert Recommendation for a plump look

30x50cm                       30x50cm*

45x45cm                       50x50cm

60x60cm                       65x65cm

70x70cm                       75x75cm

*use same size inserts in small cushions
