  Romania vs. ChadSimilarity: 100/100 · 2:3 vs. 2:3Romania and Chad both fly a 2:3 vertical tricolor of blue, yellow, and red in the exact same hoist-to-fly order, differing only in the statutory shade of their hoist blue stripe and their independent historical origins.
• 
  Monaco vs. IndonesiaSimilarity: 95/100 · 4:5 vs. 2:3Monaco and Indonesia both fly a horizontal bicolor of red over white, but Monaco's official flag uses a squarer 4:5 aspect ratio while Indonesia mandates a wider 2:3 rectangle.
