In this case,  the perfect match is a sideboard and painting or mirror. We recommend keeping proportions in mind when picking out furniture for your home so that it fits well with all other pieces of furnishing you may have collected over time. If, at first sight, they don't seem to go together as one cohesive set-up, then try looking into different options from what's already there, like adding more width onto more expansive mirrors/paintings by using an alternate shelf unit instead or vice versa.
