How to say "depth" in Japanese

• 奥行きおくゆきCommon
  nounThe physical depth of a space or object: how far back it goes, front to back. English may call this dimension depth or length, as with a room, shelf, or box.
  間口まぐちも広ひろいが奥行おくゆきも同様どうように深ぶかい。↗

  It's as deep as it is wide.
• 深度しんどCommon
  nounDepth treated as a measurement or technical figure rather than a general quality, as in the depth of the water at a given point.
• 深さふかさCommon
  nounThe general word for how deep something is, covering both physical depth (a hole, water, snow) and abstract profundity of thought, feeling, or meaning.
• 厚みあつみCommon
  nounLiterally 'thickness'; for 'depth' it is the figurative sense — profundity or richness, substance or body in something abstract such as flavor, character, or content.
• 濃淡のうたんCommon
  nounOnly for depth of flavor: literally the shading between strong and weak, it describes how rich and complex a taste is, not physical or abstract depth in general.

Choose 「奥行き」 for the front-to-back depth of a space or object, 深度 for depth as a measured figure, 「深さ」 as the all-purpose physical or abstract default, and 「厚み」 or 濃淡 only for figurative richness, chiefly of flavor or character.
