Size vs Propr: Perps Prop Firm Challenges Compared
Compare a 15-minute trading survival game with a profit-target evaluation before choosing a perps prop firm format.
By Size team
Size and Propr offer different qualification experiences for simulated funded-account opportunities. Propr positions itself as a perps prop firm and publishes profit-target challenges. Size uses a 15-minute trading survival game: finish first with a positive final score and meet the selected game’s winning rules.
If you are comparing a gamified perps prop firm challenge with an evaluation, start with the objective. A game score and a profit target are not interchangeable. Then compare the entry, account loss limits, available markets and conditions for receiving a payout.

Gamified qualification vs a profit-target evaluation
Size’s game-based qualification gives the funded challenge a defined 15-minute format. Trading performance, boosts and elimination stages affect your score and rank. A profitable virtual position alone does not establish that you won the account, and a short format does not guarantee a pass.
Propr publishes evaluation rules for its selected plans. Check the actual target, daily limit, drawdown calculation and passing conditions rather than assuming a headline plan describes every account. Read Propr’s current trading rules alongside Size’s funded challenge and account selection.
Simulated capital and trading signals
Both programs describe simulated participant accounts. Propr’s funded terms describe simulated trading data supplied to the firm, with any live replication at its discretion. That is different from personally owning a live exchange position or withdrawing the displayed account capital.
Size also states that funded balances are simulated. After a game win, eligible account profits may qualify for real cash payouts under account rules. Game profits do not carry into funded-account earnings. Read Propr’s funded terms and how simulated funded accounts work.
Perps markets and account rules
A perps prop firm label identifies a perpetual-futures focus; it does not make every market, contract or loss calculation identical. Size’s simulated funded markets span crypto, equities, commodities and indices. Check available instruments and position and leverage limits in the account.
Separate venue exposure rules from the program’s account-ending loss limits. A position can fit within a stated leverage limit while still contributing enough open loss to breach an account rule. Read Size’s funded trading guide and drawdown calculations before comparing headline balances.
Payouts and account economics
Account size, retained profit share and payout eligibility answer different questions. Compare the cost of an attempt, the amount you may lose, what earnings qualify and what account value remains after a payout. A headline reward split does not establish your likely net result after fees and unsuccessful attempts.
At Size, close all positions on the funded account before a payout request. Account deductions, wallet credit and a later external withdrawal are separate steps. Check the funded payout rules rather than treating game profit or starting capital as cash.
