Orientation (W×D×H)

Which of an item’s three dimensions, width, depth, and height, is aligned with each axis of an opening as the item is rotated to find a pose that passes.

Definition

What it means.

Orientation (W×D×H)
A single item presents up to six different cross-sections depending on how it is turned, and a fit that fails one way often succeeds another. Orientation is the bookkeeping of width, depth, and height against an opening’s axes. ItemFits tries every sensible rotation rather than assuming the upright pose, because the difference between a fail and a pass is frequently just turning the item on its side.

In depth

The fuller picture.

Six ways to present the same box

A single rigid item presents up to six different cross-sections depending on how it is turned, because each of its three dimensions can lead through an opening with either of the other two beside it. A fit that fails one way often succeeds another, so orientation is the bookkeeping of width, depth, and height against the axes of the opening. A flat, effectively two dimensional piece has just two orientations; a boxy three dimensional one has six.

ItemFits tries every sensible rotation rather than assuming the upright pose, because the difference between a fail and a pass is frequently just turning the item on its side. A tabletop that will not go through a door face on slides through easily on edge, and a tall cabinet that fails standing may pass laid down. The smallest face that can lead is usually the one that decides the verdict.

Measure it

How to measure.

  1. Measure all three item dimensions and label them width, depth, and height as the piece normally sits.
  2. Identify the smallest face, the pair of dimensions that should lead through the opening first.
  3. Test each sensible rotation against the opening, leading with that smallest face, rather than assuming the upright pose, or let ItemFits try all six for you.

In practice

How it shows up.

A tabletop that will not pass a door face-on may slide through turned on its side, which ItemFits finds by testing each W×D×H orientation.

Frequently asked

Questions we keep getting.

  • How many orientations are there?

    A boxy 3-D item has up to six distinct orientations; a flat 2-D item has two.

    01
  • Why does turning an item change whether it fits?

    Each rotation presents a different pair of dimensions to the opening, so a face that is too big one way can be small enough another.

    02
  • Which orientation does ItemFits use?

    It tests every sensible rotation and reports the one that passes, leading with the smallest face that clears rather than assuming the upright pose.
