Planning Poker Decks
Pick the right deck for your team
Every team estimates differently. Fibonacci, T-shirt sizes, risk levels, raw hours — each deck creates a different kind of conversation. Compare them and find yours.
All decks
Eight scales, one tool
From Fibonacci to T-shirt sizes, from risk levels to raw hours — Plandeck ships all eight planning poker scales out of the box. Switch decks between sessions or build your own custom scale.
Fibonacci Sequence
The most popular planning poker deck. Uses the Fibonacci sequence to reflect natural uncertainty — harder to distinguish big from bigger.
T-Shirt Sizes
Relative sizing without numeric anchoring. Great for teams new to estimation or when comparing items across projects.
Risk Assessment
Assess risk rather than effort. Useful for bug triage, security reviews, and go/no-go decisions.
Hours
Estimate in actual hours instead of abstract points. Concrete but susceptible to anchoring and individual variance.
1 to 10
Simple linear scale from 1 to 10. Familiar but creates false precision — the gap between 6 and 7 feels the same as between 1 and 2.
Powers of 2
Doubles each step, making large task boundaries explicit. Useful for teams tracking technical debt or infrastructure work.
Natural Numbers
A linear scale from 1 to 100 with common break points. Maximum flexibility, minimum opinionation.
Custom Deck
Build your own deck with any values your team agrees on. Plandeck lets you create fully custom decks for any estimation method.
Why it matters
The deck shapes the conversation
A Fibonacci deck forces teams to acknowledge that big stories are harder to scope precisely. A T-shirt deck removes the false precision that number anchoring creates. An hours deck forces accountability in client billing. The numbers on the cards aren't arbitrary — they create different kinds of friction, and different friction produces different estimates.
There is no universally right deck. The right choice depends on what you're estimating, who's in the room, and what you plan to do with the result. Each deck page below walks through the trade-offs.
