• Synonym程度ていどNeutralThe most versatile word for degree, as in 「ある程度」; after a number it is the plain way to say 'about', as in 「1時間程度」. 「レベル」 stresses grade or tier.
• Synonym水準すいじゅんWrittenLevel or standard, as in 「生活水準」; leans written and formal, where everyday speech says 「レベル」.
• Synonym次元じげんNeutralDimension or plane, as in 「次元が違う」; often figurative for a fundamentally different realm, while 「レベル」 compares heights on one scale.
• Synonym標準ひょうじゅんNeutralA standard for judging, or the average, ordinary state, as in 「標準的」; 「レベル」 says where something stands, high or low.
• Synonym級きゅうNeutralGrade or rank, as in 「一級」; typically a suffix or counter within a grading system, while 「レベル」 is not bound to any such system.
• SynonymほどNeutralDegree or amount; marks approximation as in 「10分ほど」 and comparison as in 「思ったほど」 — neither use fits 「レベル」.
• Synonym階級かいきゅうWrittenFormal word for social class, job rank or weight class, as in 「階級制」— a fixed hierarchy; 「レベル」 loosely covers how high a level is.
• Synonym等級とうきゅうWrittenFormal word for grade, as in 「一等級」; used for grading goods, stars and the like, while 「レベル」 covers level more broadly.
• SynonymクラスNeutralLoanword for a school class, and for tier or grade, as in 「トップクラス」; close to 「レベル」 in that tier sense.

• Related階かいNeutralStorey or floor, as in 「三階」, or stairs; nothing to do with ability. It meets 「レベル」 only in the sense of layers.
• Related位置付けいちづけWrittenFormal word for how something is placed and rated within the whole, as in 「重要な位置付け」; about role and positioning, not necessarily height — 「レベル」 states height directly.
• RelatedランキングNeutralLoanword for a ranking, as in 「人気ランキング」: ordering entries against each other. 「レベル」 states one's level — person, group or country — without ranking against others.
• Related層そうNeutralA stratum or group, as in 「若年層」; usually a suffix, sorting people into groups, while 「レベル」 sorts by high and low.

For the level of ability or quality, say 「レベル」 (「レベルが高い」) — the everyday default. In formal or written prose use 「水準」. For depth or degree of something, 「程度」 and 「度合い」 fit; 「程度」 is the most versatile. When the difference is one of realm rather than height, use 「次元」. For ranks and standings, 「ランク」 and 「ランキング」. Words like 「基準」 and 「標準」 are the standards you measure by, not the level itself.
