Fat-quarter square yield

See how many equal squares fit in one fat quarter before you buy.

Measurements

Editable example inputs. Adjust them for your project.

Input guidance and units

Enter inches unless a field says otherwise. The result keeps the theoretical quantity separate from purchase rounding.

Enter fractional inches as decimals: 1/8 = 0.125, 1/4 = 0.25, 1/2 = 0.5. Dimensions and yard increments use steps of 0.125; counts use whole numbers. Fraction text such as 1/8 is not accepted in number fields.

What this calculator answers

This answers how many equal squares fit within one measured rectangular fat quarter. It does not work backward from a required project count.

How to use it

  1. Measure usable fat-quarter width and length.
  2. Enter the square side.
  3. Calculate the number of same-size squares in the rectangular grid.

Formula and variables

Squares per fat quarter = floor(width ÷ square side) × floor(length ÷ square side).

Width and lengthin
Usable dimensions of this one fat quarter.
Square sidein
Side length of each identical square cut.
Yieldsquares
Count of equal squares in the simple grid.

Independent example

One usable 18 × 22 in fat quarter and 5 in square cuts.

floor(18 ÷ 5) = 3 across; floor(22 ÷ 5) = 4 along. 3 × 4 = 12 squares.

  • 12 equal squares per fat quarter

What the result means

This is a simple equal-square grid and does not report leftover dimensions, cutting waste or how many fat quarters a project needs.

Common questions

How many fat quarters do I need for a cut list?

Use the separate fat-quarter count calculator with your required square count.

Does this optimize leftover strips?

No. It reports only the equal-square grid yield.

Method notes and unresolved issues

Use measured usable dimensions and the construction method named on this page. Example inputs are optional and are not universal standards.

[待补充：核实项目元数据与当前计算输出的差异。] Catalog metadata says “unused remainder,” but the implemented result reports only square count. The page output description must be corrected; do not change the calculation.
