The catch
Canon CanoScan LiDE 300
There is no feeder, so each page has to be placed by hand.
Side by side
For occasional document and photo scans on a flat surface, the LiDE 300 will do. The LiDE 400 is worth choosing when higher optical sampling or the included upright stand has a real use in your workspace.
Before you buy
Canon’s Letter color 300 dpi timings are 10 seconds for the 300 and 8 seconds for the 400. Over 20 pages that adds up to 40 seconds of rated scanning time. Either way, you still place the page, turn it when needed and check the file.
Where this comes from
20 times 2 seconds gives 40 seconds. Manual handling is not counted, and Canon’s specified scan timing method is used.
The catch
There is no feeder, so each page has to be placed by hand.
The catch
You position each page and each back by hand.

Ordinary paperwork, detailed photo scanning and upright use are the points of contrast. The LiDE 400 adds resolution and a stand, yet you still handle pages manually.

Which one fits
Neither runs supported originals through rollers.
You position each page by hand.
An upright stand comes with the 400, subject to mode restrictions.
4800 dpi optical sampling is available only on the 400.
In practice
Canon’s Letter color 300 dpi timings are 10 seconds for the 300 and 8 seconds for the 400. Over 20 pages that adds up to 40 seconds of rated scanning time. Either way, you still place the page, turn it when needed and check the file.
20 times 2 seconds gives 40 seconds. Manual handling is not counted, and Canon’s specified scan timing method is used.
The stand included with the LiDE 400 can cut the space taken up by supported flat originals, but Canon says Auto Scan is unavailable in upright mode. Someone who wants both minimal desk use and automatic detection has to pick settings through the supported upright workflow instead.
Books and bulky originals have to lie flat in the proper way. Having a stand is no proof that every original can scan vertically.
From 2400 to 4800 dpi, the 400 doubles the maximum optical sampling. Ordinary paperwork scanned at 300 dpi gets nothing from that difference. Pick the 400 for a genuine detailed-original or enlargement task, and then check the supported scan area and the resulting file size at high resolution.
The flatbed on each measures 8.5 by 11.7 inches. Canon notes that a higher resolution can limit the scan area available.

Spec by spec
| Spec | Canon CanoScan LiDE 300 | Canon CanoScan LiDE 400 | In practice |
|---|---|---|---|
| Optical resolution | 2400 dpi | 4800 dpi | Detailed originals can benefit from more sampling, but ordinary 300 dpi documents are not automatically improved. |
| Letter color at 300 dpi | About 10 seconds | About 8 seconds | Next to positioning each page by hand, the difference is small. |
| Upright stand | Not included | Included | A different setup for suitable originals is offered by the 400. |
| Buttons | Four EZ buttons | Five EZ buttons | A separate PDF finish control is added on the 400. |
| Page handling | Manual flatbed | Manual flatbed | Neither scans a stack for you or turns a sheet over. |
Trade-offs
Change of plan
Go with Canon CanoScan LiDE 400. Beyond a small speed difference, those are concrete additions.
Go with Canon CanoScan LiDE 300. That workflow is already supported by the 300.
Neither model fits. For loose documents, pick a duplex feeder.
Decision guide
The LiDE 300 suits occasional document and photo scans on a flat surface. Go with the LiDE 400 if higher optical sampling or the included upright stand has a real use in your workspace.
For Letter color at 300 dpi, Canon's timings are 10 seconds for the 300 and 8 seconds for the 400. Over 20 pages, that adds up to 40 seconds of rated scanning time. Either way, you still place the page, turn it when needed and check the file. 20 multiplied by 2 seconds equals 40 seconds. Manual handling is excluded, and the figures follow Canon's specified scan timing method.
The stand included with the LiDE 400 can cut the space that supported flat originals take up, but Canon says Auto Scan isn't available in upright mode. Someone who wants both minimal desk use and automatic detection has to choose settings through the supported upright workflow instead. Books and bulky originals need proper flat placement. Having a stand doesn't prove every original can be scanned vertically.
The 400 doubles the maximum optical sampling, from 2400 to 4800 dpi, but ordinary paperwork scanned at 300 dpi never uses that difference. Pick the 400 for a real detailed-original or enlargement task, and then check the supported scan area and resulting file size at high resolution. Each uses an 8.5 by 11.7-inch flatbed. Canon notes that raising resolution can limit the available scan area.
