What is Stack to Pot Ratio (SPR)?
Stack to Pot Ratio (SPR) is a critical concept in poker that measures how many big blinds you have relative to the current size of the pot. It helps determine your range of playable hands and your betting strategy.

Understanding the Results
The calculator will display your SPR and provide a recommendation based on standard poker strategy:
- SPR < 1: You have less chips than the pot. This is a disadvantage position.
- SPR 1-2: Standard situation. Play standard aggressive or defensive depending on your hand strength.
- SPR 2-3: Good stack depth. You have room to play aggressively.
- SPR 3-4: Very strong stack. You can play very aggressively.
- SPR > 4: Extremely deep stack. You can be very aggressive and take control of the pot.
