What Can You Create?

Several states reviewed together

Give each panel a named interface state and show how it differs from its neighbors. A regular array supports side-by-side discussion without selecting an app's content or behavior. Use arrows and labels when the intended transition order differs from the panel's physical position on the board.

Repeated frames with a shared comparison scale

Keep the same paper frame dimensions when comparing proposed layouts so apparent size differences are intentional. The dense dots provide frequent alignment references. Record the sketch convention independently from device dimensions, since a square paper panel does not automatically represent a square display.

A board with numbered review feedback

Associate each comment with a state number and retain unresolved questions outside the panel images. The broad sheet gives room for a shared overview. Keep a dated copy of the discussion rather than treating a point-background address as a record of proposed states or reviewer decisions.

Why Users Love This Tool

Frequent references across a broad comparison board

The starting A3 stock is 297×420 mm297 \times 420\,\mathrm{mm}. Its #0A0A0A circles use 0.8pt diameter, approximately 0.282mm, at three-millimeter centers. Test a small state label and annotation against the black point layer before committing the full board. Appearance can be edited independently from the interval that controls the physical frame dimensions.

A full board count that includes shared separators

Linked 12mm borders leave 91 dot columns and 132 rows, or 12,012 complete points. Those centers provide 90×13190 \times 131 intervals. The twelve-panel array uses 84×11384 \times 113 intervals after its gutters are included. Counting the separators prevents repeated panels from quietly extending outside the available original field.

Perfect For

Product teams comparing a proposed state sequence

Name what each state is meant to show and which user action leads to another. The paper board can organize a discussion, but transitions need a prototype or implementation to be exercised. Keep that behavioral evidence separate from the static drawn-state convention.

Design educators explaining interface variation

Use equal frames to compare a selected structural change across several cases. Ask learners to label their assumptions and transitions instead of letting the array imply them. The point field supports placement rather than evaluating whether the proposed interaction or information structure works.

Facilitators retaining a review snapshot

Date the board, number each panel, and connect comments to those numbers. State which proposals remain unresolved. An annotated snapshot keeps the discussion readable later, while its saved background address allows the exact dense reference layer to be reconstructed if needed.

Worked board: twelve square state frames and intersecting gutters

Arrange three columns and four rows of twenty-six-interval square panels. Each panel measures 78×78 mm78 \times 78\,\mathrm{mm}. Two three-interval column gutters produce 3×26+2×3=843 \times 26 + 2 \times 3 = 84 intervals, or 252mm, across. Three three-interval row gutters produce 4×26+3×3=1134 \times 26 + 3 \times 3 = 113 intervals, or 339mm, vertically. Start at dot column 3 and row 6, ending at column 87 and row 119 within the 90×13190 \times 131 interval field. The twelve panel interiors contain 12×676=8,11212 \times 676 = 8{,}112 interval squares, while the bounding array contains 84×113=9,49284 \times 113 = 9{,}492. Their difference is 1,380 gutter squares. Independently, the six-interval-wide vertical gutter bands contain 678 squares and nine-interval-high horizontal bands contain 756; subtract their fifty-four intersections to get the same 1,380. Add the state sketches, labels, and transitions yourself. This square paper convention does not select a device format or create interactive screens.

How It Works

How it works in three quick steps.

1

Name the states and their comparison purpose

List the proposed states and define what should vary between them. Write the paper frame convention independently from any actual device dimensions. Decide the intended transition order before relying on the physical three-by-four array to organize the review.

2

Count shared gutters around a sample panel

Add both inter-column gaps to the width and all three inter-row gaps to the height. Try the smallest state label and an intended control outline against the dense points. Reserve feedback outside the images and define how panel numbers identify comments.

3

Retain the measured review board

Export current A3 settings, compose the panels at full-page size, and measure twenty-six original intervals as seventy-eight millimeters. Save the dated annotated board, its state key, and background settings address together after checking the final document's labels.

Download & Print

PDF for the twelve-state review copy

The original PDF preserves a 297×420 mm297 \times 420\,\mathrm{mm} A3 page with vector markers. Keep that physical boundary when adding state frames and comments. Use matching paper and Actual Size for the worked seventy-eight-millimeter panel size, then inspect both a transition label and panel number.

PNG for placing behind a proposal board

Original portrait raster dimensions are 3508×49613508 \times 4961 pixels at nominal 300 DPI. Preserve its full border-inclusive page extent when importing it. The bitmap does not encode interactive states; the composed drawing and any separate prototype carry those decisions and behavioral evidence.

SVG for separate sketches and review annotations

A vector composition can keep circles, panel images, state labels, and comments on distinct layers. Maintain the A3 physical extent through those additions. Save the annotated board separately from the blank point output so its proposed transitions and review context remain available.

Check the finished paper

  1. Match the composed A3 board to the physical paper and retain its full extent after panel sketches are added.
  2. Choose 100% or Actual Size and measure twenty-six center gaps between twenty-seven points as seventy-eight millimeters.
  3. Read the smallest state number and transition label from the intended review position on the actual finished copy.
  4. Check the twelve-frame count and shared gutter dimensions, keeping static proposal marks separate from prototype behavior evidence.

FAQ

Frequently Asked Questions

Why does the array use eighty-four by 113 intervals?
Three twenty-six-interval panel widths total seventy-eight. Two column gaps of three intervals add six, producing eighty-four horizontally. Four panel heights total 104, and three row gaps add nine, producing 113 vertically. At original three-millimeter spacing, the full array is 252 by 339mm. The arrangement fits the initial ninety-by-131 interval center span, with its original point diameter and margins retained.
How is the gutter area counted without duplicating crossings?
The complete array has 9,492 interval squares, while its twelve panel interiors have 8,112, leaving 1,380 for gutters. Counting the vertical bands gives 678 and the horizontal bands gives 756, but their fifty-four crossing squares appear in both totals. Subtract those intersections once: 678 plus 756 minus fifty-four equals 1,380. This describes the paper array's separators, not a digital layout measurement or available user-interface area.
Do square seventy-eight-millimeter panels represent actual screens?
They are a shared paper convention for the worked comparison. A real device or interface may use a different proportion and its own dimensions. Record any intended mapping separately, and change the panel allocation if another shape better communicates the proposal. The dot background neither selects a device resolution nor validates responsive behavior. Equal paper frames simply let the author compare states under a stated drawing convention.
Will the exported board allow a reviewer to click through states?
The generator exports blank points rather than an interactive prototype. State sketches, controls, transition arrows, and labels added in another application remain static annotations unless a separate tool implements their behavior. Keep that distinction visible during review and retain behavioral evidence in the actual prototype or app. The Share address reconstructs the selected reference lattice without storing panel drawings, transitions, or reviewer comments.
How should the proposal board be retained after a review?
Save the completed annotated file with its date, panel numbers, state key, and unresolved questions. Keep the selected background address alongside it so the guide layer can be reproduced. If the proposal is revised, preserve the previous discussion snapshot rather than letting a new blank export replace its context. The physical proof should include small labels and frame dimensions on the copy that reviewers actually used.

About This Tool

A3 three-millimeter black dot paper provides frequent alignment references across a large board of proposed interface states. The common point rhythm makes repeated frame dimensions countable, while the authored state labels explain what each sketch is intended to show. A regular panel array alone cannot establish a reading order, a device format, or interaction behavior. Those decisions belong in explicit annotations and, when needed, a separate working prototype.

The twelve-frame study includes the gutters in both outside dimensions and checks their area by two independent counts. The intersection correction matters because vertical and horizontal separator bands overlap. Stating those quantities keeps the full board, panel interiors, and shared gaps from being treated as the same region. Placing the complete array at known dot indices also leaves a deliberate surrounding reservation rather than assuming every available point belongs inside a screen.

The retained review record needs more than its reproducible lattice. State images, transition labels, feedback, and unresolved questions carry the proposal's meaning, while the background settings address preserves its physical reference. Test small labels against the black points and verify a panel run after the composition and print workflow is complete. Saving the dated annotated board beside that measured background keeps the static discussion evidence understandable and leaves behavioral claims to the actual prototype or implementation.
