Translation guide
The concept of granularity refers to the level of detail or coarseness in a system, data, or analysis. In Japanese, this is expressed through several terms depending on context, from technical to everyday use.
Expressing the degree of fineness or coarseness in information, measurements, or categories.
The most direct and common translation for 'granularity' in technical and business contexts. Refers to the size or level of detail of data units, particles, or categories.
データの粒度を細かくすると、分析の精度が上がります。
Increasing the granularity of the data improves the accuracy of the analysis.
このレポートでは、情報の粒度が粗すぎる。
The granularity of the information in this report is too coarse.
Literally 'fineness' or 'minuteness'. Used in everyday language to describe the level of detail, but less formal than 粒度.
この分類の細かさは十分ですか？
Is the granularity of this classification sufficient?
Means 'level of detail'. Often used in contexts like image resolution, report detail, or data precision.
画像の詳細度を上げると、ファイルサイズが大きくなる。
Increasing the granularity (detail level) of the image increases the file size.
Refers to 'fineness' or 'precision', often used in technical fields like imaging or manufacturing. Less common than 粒度.
このプリンターの精細度は非常に高い。
The granularity (resolution) of this printer is very high.
Describing the texture or particle size of materials like sand, powder, or grain.
Same word as above, but used in physical sciences and engineering for particle size distribution.
砂の粒度を測定する。
Measure the granularity of the sand.
Literally 'coarseness of particles'. Used when emphasizing the rough texture or large particle size.
この粉の粒子の粗さが気になる。
I'm concerned about the granularity (coarseness) of this powder.
Refers to a fine, smooth texture. Often used for skin, fabric, or food. The opposite of coarseness.
この豆腐のきめ細かさは素晴らしい。
The fine granularity (smooth texture) of this tofu is wonderful.
Referring to the level of detail in setting permissions, roles, or security policies.
Standard phrase in IT security contexts. Means 'granularity of access permissions'.
このシステムでは、アクセス権限の粒度を細かく設定できます。
In this system, you can set the granularity of access permissions finely.
Means 'subdivision of permissions'. Emphasizes breaking down permissions into smaller, more detailed parts.
セキュリティ向上のため、権限の細分化が必要だ。
For improved security, granularity of permissions is necessary.
粒度 (りゅうど) is the standard technical term for granularity in data, systems, and physical particles. 細かさ (こまかさ) is a more general, everyday word for fineness or detail. 詳細度 (しょうさいど) specifically refers to the level of detail, often in visual or descriptive contexts. Use 粒度 for most professional or technical situations.
データの粒度を上げる
increase data granularity
説明の細かさ
granularity of explanation (everyday)
画像の詳細度
image detail level
Do not translate 'granularity' literally as 粒状性 (りゅうじょうせい) or 顆粒性 (かりゅうせい); these are rare and refer specifically to granular physical form, not the abstract concept. Stick with 粒度 or context-appropriate alternatives.
