Definition
Range, also called spread, is the difference between the highest and lowest numbers in a draw. It measures how widely the six drawn numbers are distributed across the 1–49 pool. A range of 48 means the numbers span nearly the entire pool (e.g., 1 and 49 both drawn), while a range of 10 would mean all six numbers are clustered within a narrow 10-number window.
Why It Matters
Range is closely related to the concept of compactness. Draws with a narrow range are highly compact — all numbers are close together. This is statistically unusual because the 49-number pool is large relative to the 6 numbers drawn. Most draws naturally produce a wide spread. Selecting numbers that are all clustered together (e.g., 22-23-24-25-26-27) creates a ticket with an atypically narrow range, matching fewer than 1% of historical draw patterns.
The range metric helps players quickly assess whether a draw or selection is well-distributed or unusually compact. Our result pages display the range for every draw alongside the compactness percentage.
How It Is Calculated
Range = max(drawn numbers) − min(drawn numbers). For draw {3, 17, 24, 31, 38, 46}, range = 46 − 3 = 43. The theoretical minimum range for 6 numbers is 5 (six consecutive numbers like 10-11-12-13-14-15). The maximum is 48 (numbers 1 and 49 both drawn).
Common Misconceptions
"Wide-range draws are better." Wide range doesn't correlate with winning probability. Every valid combination has equal odds. Range simply describes the spatial distribution of the drawn numbers. However, extremely narrow ranges are rare in practice, so tickets with very compact number clusters are structurally atypical.
Practical Example
Draw A: {2, 11, 28, 33, 41, 49} → range = 47 (wide spread). Draw B: {18, 20, 22, 25, 27, 29} → range = 11 (very compact). Both draws have equal mathematical probability, but Draw B's pattern appears in fewer than 1% of historical results. Explore draw analysis on any draw result page.
Limitations
Range only measures the distance between extremes — it says nothing about how the four middle numbers are distributed. Two draws can have identical ranges but very different internal spacing. For a more complete picture, combine range with decade distribution and average spacing metrics available on our statistics page.
Expected Range Values
For 6 numbers drawn uniformly from 1-49, the expected range is approximately 41. Simulation of millions of random draws shows that roughly 70% of draws have a range between 35 and 48. Ranges below 25 occur in fewer than 5% of draws, and ranges below 15 are exceptionally rare (less than 0.5%). This means most legitimate winning combinations span a substantial portion of the number pool. A compact ticket like {20, 22, 24, 26, 28, 30} with a range of just 10 — while mathematically equally probable — is structurally anomalous relative to the vast majority of real draw outcomes.
Frequently Asked Questions
What is range in Lotto 6/49 analysis?
Range is the difference between the highest and lowest numbers drawn. For example, if the drawn numbers are 5, 12, 23, 34, 41, 48, the range is 48-5=43.
What is a typical range for Lotto 6/49?
Most draws have a range between 30 and 45. Very narrow ranges (below 20) or the maximum range (48) are less common.
Does range affect my chances of winning?
No. Range is a descriptive metric. It measures the spread of drawn numbers but has no predictive value.
