About this app

Plan every futures trade with confidence. SizeRight is a futures position size calculator that turns your sizing balance, risk percentage, and stop distance into a clear contract count before you enter a trade.

Enter your plan, choose a futures instrument, and see how many contracts fit within your selected stop-risk budget. SizeRight rounds down automatically, helping you stay within the risk you set.

PLAN A POSITION

• Calculate contract count from your sizing balance, percentage risk, and stop distance in ticks.
• See your risk budget and estimated stop risk in dollars before placing a trade.
• View stop distance in points and the cost per contract for your selected instrument.
• Automatic rounding keeps the calculated futures position within your selected stop-risk budget.
• Review calculation details to understand the numbers behind each position.

FUTURES INSTRUMENTS

SizeRight includes free micro futures contracts for popular markets, including MNQ, MES, M2K, MGC, MCL, MYM, MBT, and SIL.

Unlock Pro with one purchase to access 20 additional futures instruments, including NQ, ES, RTY, GC, CL, YM, BTC, SI, currency futures, Treasury futures, and commodity markets. There is no subscription.

BUILT FOR ACTIVE FUTURES TRADERS

Whether you trade micro futures, full-size contracts, funded-account evaluations, or your own account, SizeRight gives you a fast, structured way to plan risk before market entry.

Use it to compare setups, test different stop distances, and decide whether a position fits your rules before you place an order.

PRIVATE BY DESIGN

All calculations happen on your device. No account, login, or internet connection is required for core calculator features. SizeRight does not connect to a broker and cannot place trades.

SizeRight estimates stop risk only. Fees, slippage, gaps, margin requirements, and broker-specific rules are not included. Always confirm contract specifications and requirements with your broker before trading.
