--- title: "Random Number" description: "Create random numbers with ranges and formats" last_updated: "2026-06-19" --- # Random Number > Create random numbers with ranges and formats Pick random numbers from any range — with no repeats, sorting, and instant statistics ## What Is It? Our Random Number Generator instantly picks random numbers from any range you set, whether that's a classic 1-100, a quick 1-10 or 1-6, or anything up to 1000 and beyond. Use it for lottery and raffle draws, dice rolls and games, math practice, statistical sampling, coding test data, or any time you need to make a fair, random choice. You control the minimum, maximum, and how many numbers to draw, and you can switch off duplicates so every result comes out unique with no repeats. It works like an instant random number wheel — there's no list to type and nothing to install. ## How It Works Set your Minimum and Maximum to define the range, choose how many numbers to generate, and pick a format: Decimal, Binary, or Hexadecimal. Turn off Allow Duplicates for unique numbers with no repeats, or switch on Sort Results to order them from lowest to highest. Every draw uses a cryptographically secure random algorithm, so the numbers are unbiased, unpredictable, and impossible to rig. The tool also shows live statistics — average, minimum, maximum, and total sum — and lets you copy the results or download them as a text file. ## Key Features - **Any Custom Range** — Generate from 1-100, 1-10, 1-1000, or any custom min and max — negatives included - **Decimal, Binary & Hex** — Output numbers in decimal, binary, or hexadecimal for math, coding, and computer science - **Live Statistics** — Instant average, minimum, maximum, and total sum for every batch you generate - **No-Repeats Mode** — Switch off Allow Duplicates to draw unique numbers with no repeats for raffles and draws - **Sort & Order** — Turn on Sort Results to arrange your generated numbers from lowest to highest - **Copy & Export** — Copy results to your clipboard or download the whole list as a text file ## Use Cases - 🎲 **Games & Dice** — Roll dice, draw cards, generate loot, and power any board or party game - 🎟️ **Raffles & Lottery** — Draw fair lottery numbers, raffle winners, and prize picks with no repeats - 🔬 **Research & Sampling** — Statistical sampling, surveys, and random assignment for experiments - 💻 **Coding & Test Data** — Seed test data, IDs, and edge cases when building or debugging software - ➗ **Math & Education** — Create practice problems, quiz numbers, and examples for the classroom - 🎯 **Decision Making** — Settle a choice, pick a winner, or break a tie with an impartial number - 📊 **Spreadsheets** — A faster alternative to Excel or Google Sheets RANDBETWEEN formulas - 🔢 **PINs & Codes** — Generate 4-digit numbers, room numbers, jersey numbers, and quick codes ## Frequently Asked Questions ### What is a random number generator? A random number generator (RNG) is a free online tool that instantly produces random numbers within a range you choose. Instead of guessing or rolling dice, you set a minimum and maximum and click once to get fair, unpredictable numbers. Ours picks each number with a cryptographically secure algorithm, so every value in your range has an equal chance of appearing. ### How do I generate random numbers from 1 to 100 (or any range)? Set the Minimum and Maximum fields to your range — enter 1 and 100 for a 1-100 draw, or use values like 1-10, 1-13, 1-24, 1-50, or 1-1000 just as easily. Then choose how many numbers you want and click Generate. The range accepts any whole numbers, including negatives, so you're never limited to fixed presets. ### Can I generate random numbers with no repeats? Yes. Turn off Allow Duplicates and every number in the batch will be unique, with no repeats — perfect for raffles, team draws, and lottery picks. Keep in mind the most unique numbers you can draw equals the size of your range (max − min + 1), so a 1-10 range returns at most 10 different numbers. ### Does this work like a random number wheel or picker? It works just like a random number wheel or picker — each click randomly selects a number, or a whole batch of numbers, for you. The difference is there's nothing to spin or set up first: type your range, hit Generate, and you get an instant, unbiased result every time. ### How do I make a random number generator in Excel, Google Sheets, Python, or Java? In Excel or Google Sheets you can use =RANDBETWEEN(min, max); in Python use random.randint(min, max); in Java use the Random class or ThreadLocalRandom; and in JavaScript, Math.random(). Those work but mean writing a formula or code each time. Our free tool does the same job instantly in your browser — no spreadsheet and no scripts — and adds no-repeats, sorting, and live statistics. ### How is this different from Google's random number generator? Google's built-in random number generator gives you a quick single number between two values. Our tool does that too, but adds batch generation, a no-repeats mode, sorting, decimal/binary/hexadecimal formats, and instant statistics like average and sum — all on one page and free to use online. ### Can I generate numbers in binary or hexadecimal? Yes. Use the Number Format option to switch between Decimal (10), Binary (1010), and Hexadecimal (A). Binary is base-2 and hexadecimal is base-16, both widely used in programming, computer science, and digital electronics. ### How do I generate a 4-digit random number? Set the Minimum to 1000 and the Maximum to 9999, then click Generate for a random 4-digit number. Adjust the range for other lengths — 100-999 for 3 digits, or 10000-99999 for 5 — and turn off Allow Duplicates if you need several unique codes at once. ### Is the generator truly random, or can it be rigged? Every number is produced with a cryptographically secure random algorithm using the browser's Web Crypto API, so results are genuinely unpredictable and can't be rigged or biased toward any value. That makes it fair for lotteries, raffles, giveaways, and any draw where impartiality matters. ### Can I copy, sort, or download the numbers? Yes. Switch on Sort Results to order your numbers from lowest to highest, then copy the full list to your clipboard or download it as a text file. Each batch also shows live statistics — average, minimum, maximum, and total sum — so you can review the spread at a glance. ## Related Generators - [Random Equation](https://myrandomgenerator.com/pages/tools/equation.md) — Generate mathematical equations with solutions and step-by-step explanations - [Random Height](https://myrandomgenerator.com/pages/tools/height.md) — Generate random heights in various units and categories - [Random Percentage](https://myrandomgenerator.com/pages/tools/percentage.md) — Generate random percentages for statistics and calculations - [Random Phone](https://myrandomgenerator.com/pages/tools/phone.md) — Generate phone numbers in various international formats - [Random Name](https://myrandomgenerator.com/pages/tools/name.md) — Generate first names, last names, or full names - [Random IP Address](https://myrandomgenerator.com/pages/tools/ip.md) — Generate IPv4/IPv6 addresses with customizable options --- [Random Number & Math Generators](https://myrandomgenerator.com/pages/numbers.md) · [All generator tools](https://myrandomgenerator.com/pages/tools.md) · [Home](https://myrandomgenerator.com/pages/index.md) ## Sitemap See the full [sitemap](https://myrandomgenerator.com/sitemap.md) for all pages.
