🖼️ 论文插图分辨率计算（期刊 DPI 要求）Journal Figure DPI & Size Calculator
按 Elsevier、Nature、IEEE、Springer、ACS、Cell、PLOS 等出版社公开的单栏/双栏宽度和 300、500、1000 DPI 要求，计算插图需要的像素尺寸；拖入图片即可判断当前像素在目标宽度下的实际 DPI 和最大可印刷尺寸。Work out the pixels a figure needs for single- or double-column widths from Elsevier, Nature, IEEE, Springer, ACS, Cell, PLOS and others at 300, 500 or 1000 DPI; drop in an image to see its effective DPI at that width and the largest size it can print at.
预设来自各出版社公开的作者指南，常见要求为：照片 300 DPI、图文混合 500–600 DPI、线条图 1000–1200 DPI。期刊要求会更新，请以目标期刊最新的作者须知为准。Presets come from publishers’ public author guidelines; typical rules are 300 DPI for photos, 500–600 DPI for combination art and 1000–1200 DPI for line art. Requirements change, so always confirm with your target journal’s current guide.
使用说明与常见问题How-to & FAQ
「论文插图分辨率计算（期刊 DPI 要求）」是什么？What is the Journal Figure DPI & Size Calculator?
按 Elsevier、Nature、IEEE、Springer、ACS、Cell、PLOS 等出版社公开的单栏/双栏宽度和 300、500、1000 DPI 要求，计算插图需要的像素尺寸；拖入图片即可判断当前像素在目标宽度下的实际 DPI 和最大可印刷尺寸。Work out the pixels a figure needs for single- or double-column widths from Elsevier, Nature, IEEE, Springer, ACS, Cell, PLOS and others at 300, 500 or 1000 DPI; drop in an image to see its effective DPI at that width and the largest size it can print at.
如何使用「论文插图分辨率计算（期刊 DPI 要求）」？How do I use the Journal Figure DPI & Size Calculator?
选择期刊和版式（单栏/双栏），再选图片类型（照片 300 DPI、图文混合 500 DPI、线条图 1000 DPI），即可看到需要的像素。拖入自己的图片会显示是否达标；不达标时请从原始数据重新导出，而不是放大图片。Pick a journal and width, then the figure type (photo 300, combination 500, line art 1000 DPI) to see the pixels needed. Drop your image to check it; if it falls short, re-export from the source rather than upscaling.
把 72 DPI 的图改成 300 DPI 可以吗？Can I just change 72 DPI to 300?
只改 DPI 数值而不增加像素，印刷尺寸会变小；放大像素则不会增加细节。正确做法是用绘图软件按目标尺寸重新导出，矢量图最好导出 PDF/EPS。Changing the number without adding pixels just shrinks the print size, and upscaling adds no detail. Re-export at the target size; save plots as PDF/EPS.
预设的尺寸是最新的吗？Are the presets current?
预设来自各出版社公开的作者指南，期刊之间、年份之间可能有差异，最终请以目标期刊最新的作者须知为准。They come from publishers’ public author guides and can vary by journal and year — always confirm with the target journal.
