The grid: one square = one stitch
The whole chart is a grid, and the rule is simple: every square is one full cross-stitch on your fabric. If the chart is 120 squares wide, your finished piece is 120 stitches wide. The grid does not show the fabric's weave — it shows stitches — so a 120-wide chart looks different in size on 14-count versus 18-count aida even though the stitch count is identical.
Symbols and colors: the two ways charts are printed
Charts come in two styles, and many use both at once:
- Symbol charts put a unique black-and-white glyph (●, ▲, ✚, etc.) in each square. These print cleanly and are unambiguous even in black and white.
- Color charts fill each square with the approximate thread color. Easy to visualize, but similar shades can be hard to tell apart on paper.
The best charts are color-plus-symbol: each cell shows both, so you get the at-a-glance color and the unambiguous symbol. Photo-based patterns use a lot of shades, so a symbol per color is essential to avoid mixing up near-identical grays or browns.
The color key (the legend)
Beside or below the chart is the key — a table that translates the chart into thread. For each symbol it lists:
- The symbol as it appears on the grid.
- The DMC number (and often the color name) to buy and stitch with.
- Sometimes the stitch count or number of skeins needed for that color.
Work with the key next to you. When you see ▲ in a square, you check the key, find ▲ = DMC 310 (Black), and stitch that square in black.
Bold lines and center arrows
Two navigation aids keep you from miscounting:
- Bold grid lines every 10 squares divide the chart into 10×10 blocks so you can count "three blocks over, two down" instead of counting single squares across a whole row.
- Center arrows on the edges mark the horizontal and vertical middle. You almost always start stitching from the center of the design, matched to the center of your fabric, so the finished piece ends up centered with even margins.
Backstitch and special stitches
Not every line on a chart is a cross-stitch. Solid straight lines drawn over the grid (not inside squares) are backstitch — outlines and fine details worked after all the cross-stitches, usually with a single strand. You may also see fractional stitches (¼, ½, ¾) on curved or detailed patterns, and French knots shown as filled dots in the key. Photo patterns are mostly full cross-stitches, which is part of why they're beginner-friendly.
A simple reading routine
Put it together: find the center arrows, start there, and work one color or one 10×10 block at a time. Keep the key visible, count against the bold lines, and tick off blocks as you finish them. Save any backstitch for the very end. That routine turns even a dense, multi-color photo chart into a series of small, countable sections.
Frequently asked questions
What do the symbols on a cross-stitch pattern mean?
Each symbol represents one thread color. The key beside the chart tells you which DMC floss number each symbol maps to, so ✚ might mean DMC 310 black and ● might mean DMC 3823 pale yellow.
Where do I start stitching on a pattern?
Almost always from the center. Find the center arrows on the chart edges, match them to the center of your fabric (fold it in quarters to find it), and work outward so the design ends up centered.
What are the bold lines on a cross-stitch chart?
They divide the grid into 10×10 blocks so you can count position quickly and accurately. They are counting aids only — they are not stitches.
What do straight lines over the grid mean?
Those are backstitch: outlines and fine details stitched after the cross-stitches, usually with a single strand of floss. They sit on the lines of the grid, not inside the squares.
