Multi-Panel Figure Maker
Assemble Multi-Panel Figures for Publication
FigureGuild's Figure Assembler combines your individual charts and images into a single, journal-ready multi-panel figure — with automatic panel labeling and journal-width presets, no design software required.
Build the figure your paper needs
Arrange panels in a grid, place your charts and microscopy/gel images into panels, and assemble a clean multi-panel layout (Figure 1, Figure 2...) ready for submission.
A multi-panel figure combines two or more data panels (charts, images, diagrams) labeled A, B, C, etc. into a single submission-ready figure file. In most journals, a paper's main figures contain 4–8 panels each, assembled within the journal's column width.
Automatic A/B/C/D labeling that stays in order
Panels are labeled automatically and labels stay in reading order — so your manuscript references (Fig. 1A, 1B) always match. No manual text boxes, no misaligned labels, no numbering errors.
Labels are editable text, never baked into an image. You can adjust the font, size, or position of any panel label after layout — without regenerating the figure.
Journal-width presets
Lay out figures at the exact column widths journals require — so the figure fits first time. No guessing, no resizing after submission.
Nature
89 mm single column, 183 mm full
Cell
85 mm single column, 174 mm full
Science
90 mm single column, 190 mm full
PNAS
89 mm single column, 180 mm full
Editable, never rasterized
Panel labels and captions stay editable text; the layout stays editable in-app. Export at journal DPI (PNG, PDF, SVG, TIFF). You never need Illustrator to fix a label.
Unlike tools that export a flat raster image, FigureGuild keeps your figure as editable vector text and shapes. Adjust any panel label, caption, or spacing after layout without starting over.
Works with your existing figures
Import charts you built in FigureGuild's Graph Builder, or upload your own images — microscopy, gels, diagrams, anything (up to 50MB) — and assemble them into one figure.
FigureGuild normalizes all panels to the same physical dimensions, applies uniform spacing and labeling, and produces a single file at the journal's required DPI.
Common multi-panel figure layouts
1 × 2 (side-by-side)
Two equal-width panels. Most common for comparing a representative image with a quantification chart.
1 × 3 (three across)
Three equal panels in a row. Common for comparing three conditions or three experimental outcomes.
2 × 2 grid
Four equal panels. Efficient use of full-width space for four related experiments.
Wide + 2 stacked
A large panel (A) with two stacked smaller panels (B, C) to its right. Shows a primary result with two supporting panels.
3-row layout
Six panels in two columns. Common for full-width figures with extensive data.
Custom
Any combination: mix different panel sizes and orientations within the journal column width.
Multi-panel figure rules for publication
- Panel labels: Uppercase bold A, B, C inside the figure boundary at the top-left of each panel. Minimum 8–10 pt at print size.
- Spacing: 2–4 mm between all panels, consistent throughout the figure.
- Color consistency: The same color represents the same experimental group in every panel and every figure in the paper.
- Font consistency: The same font (Arial/Helvetica) and size for axis labels across all panels.
- Axis alignment: If panels share an x- or y-axis variable, align the axes to the same range where scientifically appropriate.
- Scale bars: Required in every microscopy or image panel, labeled with value and unit in the figure legend.

Frequently asked questions
How do I combine multiple charts into one figure?
Drag your individual charts or images into FigureGuild's Figure Assembler. Arrange them in a grid, choose a layout (1x2, 2x2, 3-row), and the tool labels panels A, B, C automatically. Export as a single figure at your journal's required DPI and column width.
Does it label panels automatically (A, B, C)?
Yes. Panels are labeled automatically and stay in reading order — so your manuscript references (Fig. 1A, 1B) always match. Labels are editable text, never baked into an image.
Can I match my journal's figure width?
Yes. FigureGuild includes presets for Nature (89 mm single column, 183 mm full), Cell (85 mm), Science, PNAS, eLife, and PLOS. Pick your journal and the layout is set to the exact width required.
Can I import my own images?
Yes. Import charts you built in FigureGuild's Graph Builder, or upload your own microscopy images, gels, diagrams, and other figures (up to 50MB). Combine them all into one publication-ready multi-panel figure.
