About the BMW 3 Series Touring 2023 boot
Start with the floor in the 3 Series Touring boot. With the rear seats up it is 39⅜″ long, and it narrows to 37⅜″ across. That holds a couple of medium boxes next to each other. Fold the seats and you have 68⅞″ (29½″ more) for long flat packs. The opening is 39⅜″ wide and gives 28″ of clear height above the loading sill. Lifting is easy here: the sill is only 23⅝″ off the ground, and the drop to the floor is just ⅜″. With the seats up, push each box right up to the seat backs before you slide in the next.
About the BILLY Bookcase, white, 31 1/2x11x79 1/2″ package
The white BILLY is packed in one long, narrow box: 81¼″ × 11¾″ × 5″. It weighs 88 lb 1 oz, and at that length you want a second person to carry it. Loaded end first, it asks little of the opening: only room for its 11¾″ by 5″ end. Lying flat and straight, it needs 81¼″ of floor for the longest side. On its side and at an angle, it needs less floor but more width at the opening, and the verdict on this page shows whether that works in your boot. Lift it level between the two of you and keep it that way until the whole box is in the boot.
