Bangkok offers the wider top tier and easier day-to-day expat logistics. New Delhi is cheaper across most fee bands and provides a stronger AP and American pathway through AES. Both cities have mature international school provision from early years to age 18, but air quality is the decisive variable for many families.
Schools landscape side by side
Bangkok's international market is the larger of the two by school count, with more than 200 fully accredited schools. The shortlist parents recognise includes Bangkok Patana, NIST International School, International School Bangkok, Shrewsbury International School and Harrow Bangkok. NIST and Patana run full IB continuums; Shrewsbury and Harrow follow the English National Curriculum to A Level; ISB blends American with IB Diploma and AP options. Apply twelve to eighteen months ahead for Years 1, 2 and 7 at the top names. See our Bangkok city guide for the full school landscape.
New Delhi's expat bench is led by the American Embassy School (AES), British School New Delhi, Pathways World School and Step by Step World School. AES is the long-standing premium choice for US curriculum families. British School Delhi follows the English National Curriculum to A Level and IGCSE. Pathways and Step by Step offer full IB continuums. Availability at AES and BSND is competitive in Year 7 but better than Bangkok's Tier 1 at most other entry points.

Fees and value for money
Premium Bangkok schools publish 2026 senior fees from THB 800,000 to THB 1,200,000 (roughly USD 22,000 to USD 33,000). Mid-tier IB and British schools run THB 500,000 to THB 800,000. Add 15 to 25 percent for capital levies, transport, lunches and external exam costs. See our Bangkok fees guide for the all-in five year load.
New Delhi spans a wider fee range. AES publishes 2026 senior fees of USD 22,000 to USD 38,000, the highest in the city. British School Delhi runs INR 7,00,000 to INR 14,00,000 (USD 8,500 to USD 17,000). Pathways and Step by Step IB streams land between INR 8,00,000 and INR 16,00,000. Many families on local hire packages send children to high-end CBSE or ICSE schools at a fraction of the international rate.
Curriculum availability
Both cities cover British, IB and American pathways at scale. Bangkok has more depth in the British curriculum and a wider IB Diploma bench. New Delhi has a stronger American pathway through AES, including AP courses with consistently high cohort outcomes. The CBSE and ICSE systems are also available in Delhi and matter for families who may stay in India long-term.
Neighbourhoods families pick
Bangkok families cluster around Sukhumvit (Phrom Phong, Thong Lor, Ekkamai) for British and IB schools, Nichada Thani in Pakkret for ISB, and along Ramkhamhaeng or Bang Na for Harrow and St Andrews. A three-bedroom family condo in central Sukhumvit runs THB 80,000 to THB 160,000 per month; a detached compound house out near ISB runs THB 60,000 to THB 110,000.
New Delhi families pick Vasant Vihar, Shanti Niketan and Westend for AES and BSND access, with newer expat clusters in Gurgaon (DLF Phase 1, 2 and 5) for Pathways and Heritage Xperiential. A four-bedroom rented house in Vasant Vihar runs INR 4,00,000 to INR 8,00,000 per month; equivalent Gurgaon villa rentals are INR 2,50,000 to INR 5,00,000.
Lifestyle and climate
Bangkok wins on healthcare depth, food culture, international air links and weekend access to islands. New Delhi wins on space per family, lower household costs and the cultural depth of being based in one of Asia's most layered capitals. Air quality is the defining variable: Delhi's winter pollution regularly enters hazardous territory from October to February, while Bangkok's PM2.5 spikes are shorter and less severe.
Verdict: who picks which city
Choose Bangkok if you want the deepest Tier 1 school bench in Southeast Asia, reliable air quality and easier weekend logistics. Choose New Delhi if you want strong American programme access via AES, lower household costs and the cultural depth of India for older children. Most families we work with run both cities through the cost calculator before committing.
