San Francisco is the bigger city: about 873k people versus Chiang Mai's 200k — roughly 4.4× larger.
City-proper / metro population estimates. Size is one input — scroll on for cost of living, salary equivalence and quality-of-life scoring.
National income
Is Chiang Mai richer than San Francisco?
The two sit on different measures, so we are not ranking them: Thailand is reported as income per capita (GNI, PPP) ($23,960), United States as average annual wage ($82,933). A full-time wage and a whole-population income per head are not the same quantity.
Country-level figures — Chiang Mai is not Thailand and San Francisco is not United States, and both cities typically pay above their national average. Gross, before tax: see take-home pay by country for what lands in the account.
Distance
How far is Chiang Mai from San Francisco?
Chiang Mai is about 12,380 km (7,690 mi) from San Francisco in a straight line — roughly 15 h 20 m of nonstop flight time.
Great-circle distance, not a routed itinerary; flight estimate assumes ~850 km/h cruise plus 45 minutes of taxi, climb and descent.
Climate
Is Chiang Mai warmer than San Francisco?
Chiang Mai is the warmer city: January highs average 30°C vs 14°C, and July 31°C vs 21°C. San Francisco gets noticeably more sun — about 400 more sunshine hours per year.
| Month | Chiang Mai | San Francisco |
|---|---|---|
| January (high / low) | 30° / 14°C | 14° / 8°C |
| July (high / low) | 31° / 24°C | 21° / 13°C |
Tropical savanna in the northern hills — cool dry season Nov-Feb (the nomad high season), then the Feb-Apr burning-season haze, then monsoon.
Famously mild and foggy. Almost no extremes — summers are cool (rarely above 25°C), winters mild and wet. Microclimates within the city vary wildly.
Chiang Mai scores 6.2 versus San Francisco's 4.4, suggesting the Thai city offers substantially better livability or value for the factors measured here.
That 1.8-point advantage is larger than typical city comparison gaps, indicating these metros diverge meaningfully on core metrics rather than splitting hairs.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Chiang Mai | San Francisco | Winner |
|---|---|---|---|
| Affordability | 8.6 | 1.1 | Chiang Mai +7.5 |
| Quality of life | 6.0 | 6.0 | Chiang Mai +0.0 |
| Remote-work friendliness | 7.2 | 7.0 | Chiang Mai +0.2 |
| Healthcare | 4.8 | 6.0 | San Francisco +1.2 |
Each axis is a weighted aggregate of underlying indicators normalized to a 0–10 scale. Weights are explicit and disclosed per axis. The composite is the unweighted mean of the four axes — axes are not collapsed further because the underlying trade-offs (e.g. low cost vs poor air quality) are user-dependent.
Affordability
- Cost-of-living index (weight 60%)16
- Rent index (weight 40%)10
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Chiang Mai: ((100 − 16)/100 × 0.6 + (100 − 10)/100 × 0.4) × 10 = 8.6.
Chiang Mai sits well below the New York baseline on both cost-of-living and rent. Budgets stretch further here than in benchmark Tier-1 cities.
Quality of life
- Safety index (weight 40%)68
- Healthcare index (weight 35%)68
- Air quality index (weight 25%)35
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Chiang Mai: (68/100 × 0.4 + 68/100 × 0.35 + 35/100 × 0.25) × 10 = 6.
Chiang Mai has a mixed quality profile. Safety: good; healthcare: good; air: fair. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)150 Mbps
- Effective income tax (lower = better) (weight 30%)5.0%
- Cost-of-living (lower = better) (weight 25%)16
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Chiang Mai: (min(150/300, 1) × 0.45 + (1 − 0.05) × 0.3 + (100 − 16)/100 × 0.25) × 10 = 7.2.
Chiang Mai combines fast internet (150 Mbps median), a 5% effective income tax and cost index 16 — a strong configuration for remote workers earning in a stronger currency.
Healthcare
- Healthcare quality index (weight 70%)68
- Healthcare out-of-pocket / month (lower = better) (weight 30%)1126
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Chiang Mai: (68/100 × 0.7 + max(0, 1 − 1126/500) × 0.3) × 10 = 4.8.
Chiang Mai has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~1126 THB/month. Cross-border insurance closes the gap.

Where each city's money goes
Two cities can have the same monthly total but very different shapes — one might burn 50% on housing while the other splits more evenly. The composition matters as much as the headline.
The biggest shape difference is housing: San Francisco spends 23.8 percentage points more of its budget on it (70% vs. 46%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Chiang Mai ↔ San Francisco
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Chiang Mai = 16, San Francisco = 90); currency-converted at 1 USD = 33.5947 THB. Tax differences are not modeled.
| Chiang Mai gross | San Francisco equivalent |
|---|---|
| THB 40,000 | $6,697 |
| THB 75,000 | $12,558 |
| THB 120,000 | $20,092 |
| San Francisco gross | Chiang Mai equivalent |
|---|---|

| $75,000 | THB 447,929 |
| $120,000 | THB 716,686 |
Equivalence here means same cost-of-living purchasing power, not same net take-home. Effective tax rates differ between countries; a salary equivalent on cost can still net more or less depending on the destination's tax regime. Use the calculator for tax-adjusted figures at a specific lifestyle tier.

Remote work logistics
Time zones and language: Chiang Mai vs San Francisco
Chiang Mai (Asia/Bangkok) and San Francisco (America/Los_Angeles) sit 15 hours apart in standard time. A 9-to-5 in one overlaps the other's for 0 hours a day — fully asynchronous collaboration. Note: San Francisco observes daylight saving while Chiang Mai doesn't, so the gap shifts by an hour part of the year.
Official: Thai · English: Moderate · Local language: Helpful
The nomad/expat economy makes English moderately usable in Nimman and the old city; Thai is needed for admin and endears you everywhere. Northern Thai (Kham Mueang) is the local flavor.
Official: English · English: Native-equivalent · Local language: Not needed
English-native. Significant Spanish and Mandarin presence in specific neighborhoods (Mission, Chinatown). English universal.

How this page is calculated
Data sources
- Mundevo per-city dataset. Cost basket, rent index, safety, healthcare, air quality and median internet for both cities. Reference date: 2026-06-10 (Chiang Mai) and 2026-05-28 (San Francisco).
- FX rate. 1 USD = 33.5947 THB, used to normalize cost baskets.
- CityScoreCalculator. Four axes (Affordability, Quality of life, Remote work, Healthcare) computed with explicit weights and explanations. See per-axis calculation strings rendered on this page.
- ComparisonService. Per-category cost deltas (housing, food, transport, utilities, leisure, healthcare) normalized to the origin currency.
Update cadence
Data as of . Last reviewed .
Calculation
For each of the four axes we compute an independent 0–10 score using the formulas printed beside each axis. The composite is the unweighted mean of the four axes. The overall winner is the city with the higher composite, unless the margin is under 0.05 points — in which case Chiang Mai is shown first as a tiebreaker to keep results stable.
Limitations
- Climate is not scored — we don't yet hold a maintained climate dataset, so weather-driven preferences are not modeled.
- Tax differences between cities in the same country are not modeled (Spain and Germany don't have material regional differences for this dataset).
- Indices are population-level. Personal cost varies with neighborhood, employer benefits and family status.
- Quality-of-life axis weights (safety 0.4 / healthcare 0.35 / air 0.25) are editorial defaults — readers with strong preferences should re-weight manually.
