This study aims to determine the effect of capital structure and profitability on firm size in energy sector companies, Oil and Gas sub-sector, listed on the Indonesia Stock Exchange (IDX) during the 2022–2025 period, both partially and simultaneously. Capital structure is proxied by Debt to Equity Ratio (DER), profitability by Return on Assets (ROA), and firm size by Ln Total Assets. This study uses a quantitative approach with secondary data. Using purposive sampling, 12 companies were selected, resulting in 50 observations. Results show that capital structure has no significant effect on firm size (sig 0.889 > 0.05). Profitability has a positive and significant effect on firm size (sig 0.022 < 0.05). Simultaneously, capital structure and profitability significantly affect firm size (sig 0.045 < 0.05) with an R Square of 0.110 (11.0%).
