Aspect Fit vs Fill Calculator
Place source content into a target frame and compare 'fit' (letterbox, no crop) versus 'fill' (crop, no bars) — scale factors and lost pixels for both.
'Fit' (object-fit: contain) scales until the whole image is visible and adds bars; 'fill' (object-fit: cover) scales until there are no bars and crops the overflow. This gives both scale factors so you can decide between losing edges and adding mattes when repurposing a frame.
